A) That the search warrant was similar to using a high-powered telescope to look through someone's window, and that there was no problem with the activities of law enforcement.
B) That law enforcement acted properly only because there was a clear and present danger based upon the presence of minors in the neighborhood.
C) That law enforcement acted properly only because the defendant, Kyllo, was a previously convicted felon.
D) That law enforcement acted properly both because there was a clear and present danger based upon the presence of minors in the neighborhood and because the defendant, Kyllo, was a previously convicted felon.
