¶2Defendant James Govens was charged with delivery of a controlled substance in violation of 35 P.S. §780-113(a)(30) and tampering with physical evidence in violation of 18 Pa.C.S. §4910. On September 24,1990, a motion to suppress physical evidence filed by defendant was heard by this court and was subsequently denied by this court. On March 13, 1991, after a trial before this court sitting without a jury, defendant was found guilty of all charges against him. On June 12, 1991, defendant’s post-trial motions were denied by this court, and pursuant to the mandatory minimum sentencing provisions of 18 Pa.GS. §7508(a)(3)(ii), defendant was sentenced to three to six years imprisonment for the drug charges and given a sentence of “guilty without further penalty” for the charge of tampering with physical evidence.
¶3FINDINGS OF FACT
¶4The credible evidence presented at the hearing on the motion to suppress established that on September 21, 1988, Philadelphia Police Officer William Brunswick, acting in an undercover capacity, knocked on the door to a first floor apartment at 2334 North 20th *517Street in the city of Philadelphia.
¶5The officers did not obtain any arrest warrant or search warrant prior to entering the apartment in which defendant was arrested.
¶6DISCUSSION
¶7The first issue presented by this case is whether, under the particular facts and circumstances of this case, the U.S. Constitution or the Constitution of the Commonwealth of Pennsylvania required the police to obtain a warrant prior to entering the residence to arrest defendant. For the reasons set forth below, this court does not believe that a warrant was required for the officers to effect the entry to arrest which was made in this case.
¶8The protection of persons against unreasonable invasions of their residences is indisputably a core objective of the Fourth Amendment to the U.S. Constitution and of Article I, section 8 of the Constitution of the Commonwealth of Pennsylvania.
¶9Recognizing the centrality of this protection against unreasonable entries into residences to our federal and state constitutional schemes, both the U.S. Supreme Court and the Pennsylvania Supreme Court have drawn a “firm line” against warrantless entries at the threshold to a residence, holding that absent exigent circumstances,
¶10*519The rationale for this firm line at the threshold was clearly articulated by the U.S. Supreme Court in Payton v. New York, 445 U.S. 573, 589, 100 S.Ct. 1371, 1381-82, 63 L.Ed.2d 639, 653 (1980):
¶11“The Fourth Amendment protects the individual’s privacy in a variety of settings. In none is the zone of privacy more clearly defined than when bounded by the unambiguous physical dimensions of an individual’s home — a zone that finds its roots in clear and specific constitutional terms: ‘The right of the people to be secure in their ... houses ... shall not be violated.’” (emphasis added)
¶12Payton’s rationale for the firm line at the threshold of residences follows the Fourth Amendment analysis set forth by the U.S. Supreme Court in its seminal decision in Katz v. United States, 389 U.S. 347, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967). In Katz, the court explained:
¶13“[T]his effort to decide whether or not a given ‘area,’ viewed in the abstract, is ‘constitutionally protected’ deflects attention from the problem presented by this case. For the Fourth Amendment protects people, not places. What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection.... But what he seeks to preserve as private, even in an area accessible to the public, may be constitutionally protected.” 389 U.S. at 351-52, 88 S.Ct. at 511, 19 L.Ed.2d at 582.
¶14*520Justice Harlan’s frequently-quoted concurring opinion in Katzexplained:
¶15“As the court’s opinion states, ‘the Fourth Amendment protects people, not places.’ The question, however is what protection it affords to those people. Generally, as here, the answer to that question requires reference to a ‘place.’ ... Thus a man’s home is, for most purposes, a place where he expects privacy, but objects, activities or statements that he exposes to the ‘plain view’ of outsiders are not ‘protected’ because no intention to keep them to himself has been exhibited. On the other hand, conversations in the open would not be protected against being overheard, for the expectation of privacy under the circumstances would be unreasonable.” 389 U.S. at 361, 88 S.Ct. at 516, 19 L.Ed.2d at 588.
¶16In United States v. White, 401 U.S. 745, 751-52, 91 S.Ct. 1122, 1126, 28 L.Ed.2d 453, 458-59 (1971), the Supreme Court adopted the second part of Justice Harlan’s analysis in his concurring opinion in Katzas the means by which expectations of privacy are to be evaluated for Fourth Amendment purposes.
¶17“Our problem is not what the privacy expectations of particular defendants in particular situations may be ... [o]ur problem, in terms of principles announced in Katz, is what expectations of privacy are constitutionally ‘justifiable’ — what expectations the Fourth Amendment will protect in the absence of a warrant.”
¶18The method of analysis which Pennsylvania’s appellate courts have employed is in accordance with that of the U.S. Supreme Court. As the Superior Court explained in Commonwealth v. Peterson, 408 Pa. Super. 22, 26, 596 A.2d 172, 174 (1991):
¶19“The Fourth Amendment guarantees ‘[t]he right of the people to be secure in their persons, houses, papers *521and effects, against unreasonable searches and seizures.’ Our courts consistently have held that the application of the Fourth Amendment depends upon whether the person invoking its protection has a ‘justifiable,’ ‘legitimate’ expectation of privacy that has been invaded by government action. See, e.g., Commonwealth v. Oglialoro, 525 Pa. 250, 256, 579 A.2d 1288, 1291 (1990). (‘The controlling consideration is whether the individual contesting the search and seizure entertains a legitimate expectation of privacy in the premises or area searched.’); see also Commonwealth v. Brundidge, 404 Pa. Super. 106, 113, 590 A.2d 302, 305-306 (1991); Smith v. Maryland, 442 U.S. 735, 740, 99 S.Ct. 2577, 2580, 61 L.Ed.2d 220 (1979); Rakas v. Illinois, 439 U.S. 128, 143, 99 S.Ct. 421, 430, 58 L.Ed.2d 387 (1978). The individual’s actual or subjective expectation of privacy alone does not control whether constitutional protection will be extended. See e.g., Hudson v. Palmer, 468 U.S. 517, 525-526, 104 S.Ct. 3194, 3199 n.7, 82 L.Ed.2d 393 (1984); Commonwealth v. Copenhefer, 526 Pa. 555, 561, 587 A.2d 1353, 1356 (1991). As Mr. Justice Powell noted in his concurring opinion in Rakas, ‘it is not enough that an individual desired or anticipated that he would be free from governmental intrusion.’ Rakas v. Illinois, 439 U.S. at 151-152, 99 S.Ct. at 434-35 (Powell, J., concurring). The test of legitimacy is not, and could not be, whether the individual hopes to conceal his activity. See Commonwealth v. Copenhefer, 526 Pa. at 561, 587 A.2d at 1356 (‘A defendant’s attempt to secrete evidence of a crime is not synonymous with a legally cognizable expectation of privacy.’); see also Oliver v. United States, 466 U.S. 170, 182-183, 104 S.Ct. 1735, 1743, 80 L.Ed.2d 214 (1984). In order to claim Fourth Amendment protection, an individual’s expectation of privacy must be one that society is pre*522pared to recognize as reasonable. See Katz v. United States, 389 U.S. 347, 361, 88 S.Ct. 507, 516, 19 L.Ed.2d 576 (Harlan, J., concurring). The resolution of this issue depends upon the totality of the circumstances and ultimately rests upon a balancing of the societal interests involved. Hudson v. Palmer, 468 U.S. at 527, 104 S.Ct. at 3200; Rawlings v. Kentucky, 448 U.S. 98, 100 S.Ct. 2556, 65 L.Ed.2d 633 (1980).”
¶20Thus, the question presented by the case at bar is whether our society is prepared to recognize as “constitutionally justifiable” or “legitimate” an assertion of “privacy” by a person whose assertively-private activity consisted of hiding behind the doorway of a residence while passing drugs beyond the threshold of the residence to whomever knocked on the door and put money through the hole in the door. This court believes that to recognize such an assertion of privacy as justifiable or legitimate would be folly.
¶21The defendant in the case at bar made no effort to keep his criminal activity private. Rather, he was engaged in the open sale of cocaine to the drug-purchasing public. Defendant cannot logically assert a reasonable expectation of privacy as to an activity which defendant chose to expose to the open view of the public. In the words of Katz: “What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection....” 389 U.S. at 351, 88 S.Ct. at 511, 19 L.Ed.2d at 582. Defendant wishes to assert the inviolability of his threshold at the same time that he violates that threshold with his felonious activity.
¶22This court is not unmindful of the need for clear rules so that law enforcement officials may understand what is permissible and what is not under the Fourth Amendment and Article I, section 8 of our *523Commonwealth’s Constitution. This court is also not unmindful of the great value which the firm line against crossing the threshold without a warrant has served and will continue to serve in many other contexts. However, we should not be so inflexible in applying the “firm line at the threshold” rule as to lose sight of the fact that the Fourth Amendment’s object is to protect persons exhibiting legitimate expectations of privacy. This court believes that to hold, as this court has in the case at bar, that a person who engages in felonious criminal conduct which crosses the threshold of his residence into a public area is subject to immediate
¶23It may be argued that this decision represents a willingness to erode our constitutional protections in an improvident overreaction to the drug problems of today’s inner cities. Instead, this court believes that *524this decision represents a considered application of the Fourth Amendment’s rationale to the case at bar.
¶24Moreover, it should be noted that the U.S. Supreme Court has permitted warrantless entries to arrest where, as in the case at bar, to hold otherwise would be to convert the Fourth Amendment from a constitutional provision designed to protect persons’ legitimate expectations of privacy to a constitutional provision which turns upon doctrines of trespass and property law developed to serve other legal purposes. For example, the U.S. Supreme Court’s decisions in Warden v. Hayden, 387 U.S. 294, 87 S.Ct. 1642, 18 L.Ed.2d 782 (1967), and in United States v. Santana, 427 U.S. 38, 96 S.Ct. 2406, 49 L.Ed.2d 300 (1976), reflect that in the case of a “hot pursuit,” the threshold will not always be an absolute barrier to a warrantless entry for arrest.
¶25For the foregoing reasons, this court believes that the officers needed no warrant to enter the apartment to arrest defendant. The drugs were recovered as a result of a lawful plain view observation, and the ring and money were recovered as a result of a search incident to a lawful arrest. Accordingly, this court believes that it properly denied defendant’s motion to suppress physical evidence.
¶26Defendant also argues that the evidence introduced at trial was insufficient to support defendant’s conviction for tampering with physical evidence in violation of 18 Pa.C.S. §4910. This section of the Crimes Code provides that a person commits a misdemeanor of the second degree “if, believing that an official proceeding or investigation is pending or about to be instituted, he ... alters, destroys, [or] conceals any ... thing with intent to impair its availability in such proceeding or investigation....” This court believes that defendant’s efforts to flush cocaine down a toilet after the police *525had knocked on his door and identified themselves as police falls within the proscription of this statute.
¶27For the foregoing reasons, this court believes that defendant’s contentions on appeal should be rejected.
¶28. Defendant was granted bail pending his appeal.
¶29. Defendant’s statement of matters complained of on appeal was not filed by counsel until February 9, 1991.
¶30. Unless otherwise indicated, all references to notes of testimony are to the notes from the hearing on the motion to suppress held September 24, 1990.
¶31. This court does not believe that the entry to arrest which was made in the case at bar can be justified under the “exigent circumstances” exception to the warrant requirement as developed by the appellate courts of this Commonwealth. Commonwealth v. Lopez, 525 Pa. 185, 579 A.2d 854 (1990); Commonwealth v. Williams, *519483 Pa. 293, 396 A.2d 1177 (1978); Commonwealth v. Peterson, 408 Pa. Super. 22, 596 A.2d 172 (1991); Commonwealth v. Rispo, 338 Pa. Super. 225, 487 A.2d 937 (1985).
¶32. Payton v. New York, 445 U.S. 573, 590, 63 L.Ed.2d 639, 653, 100 S.Ct. 1371, 1382 (1980); Commonwealth v. Williams, 483 Pa. 293, 396 A.2d 1177 (1978).
¶33. It should be noted that in Payton v. New York, supra,and its companion case, Riddick v. New York, 445 U.S. 573, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980), the warrantless entries which were invalidated were to make arrests for criminal activity which occurred two days prior to the/entry in Paytonand approximately three years earlier in RiddickIn the case at bar the only interval between defendant’s public display of criminality and his arrest was the 15 to 20 minutes that it took the undercover officer to report to his backup team and for the backup team to make the arrest.
