F I L E D United States Court of Appeals Fifth Circuit IN THE UNITED STATES COURT OF APPEALS March 27, 2003 FOR THE FIFTH CIRCUIT Charles R. Fulbruge III Clerk No. 02-10114 UNITED STATES OF AMERICA, Plaintiff-Appellee, versus MICHAEL McGRATH, Defendant-Appellant. Appeal from the United States District Court For the Northern District of Texas (3:01-CR-183-1) Before JOLLY, HIGGINBOTHAM, and MAGILL*, Circuit Judges. PER CURIAM:** We agree with the district court that the decision of the police officers to “knock and talk” was reasonable on these facts. The officers did not smell the odor produced by the manufacture of methamphetamines, nor see the two anhydrous ammonia tanks on the porch until they had exited their unmarked car and were approaching * Circuit Judge of the Eighth Circuit, sitting by designation. ** Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5TH CIR. R. 47.5.4. the front door of the house. While this confirmed the informant’s tip and made plain that the officers had probable cause to search, they were at this point committed to the course which followed. No warrant is required to “knock and talk.” At the same time, police officers who possess probable cause cannot avoid their obligation to obtain a warrant by creating exigent circumstances. While this is a close case, we are not prepared to say that the district court was in error. AFFIRMED. 2
