Depends what "actions" you are taking. In the United States, if your house is raided by law enforcement acting in good faith with a warrant, valid or not, evidence they collect during the raid will be admissible against you.
Well, unless something incredibly hairy goes down. But I'm reasonably certain arrests for child pornography don't go down like raids on hostile gang hideouts...
Possible explanation for your post: you are a cop apologist who doesn't know what he is talking about.
Furthermore, you shouldn't let the thugs rule you. Talk about exactly how you feel in as public a forum as possible.
