>If Regular police enter in someone house because domestic dispute or any similar insignificant reason and see drugs, weapons or any other criminal stuff, they have right to arrest householder and seize evidence, even if they come from completely different reasons. Different matter altogether than a warrant-based search. This would be using the "Plain Sight Doctrine" in an entry based on what the legal folks call "exigent circumstances." I recommend that you look up those two terms and read a few paragraphs before you respond, so as to not waste my time and energy. Thanks.
