So you're not okay with the Federal Government going on a manhunt? What's wrong with letting them go into your house for 2 seconds and look around and then just leave? If you have nothing to hide then there's nothing to worry about. You do NOT interfere with a Federal investigation. If they tell you they need to search your house you stand the hell aside and let them in. They aren't going to wreck it. The most they do is leave dirt on the floor but they move fast and then leave. Calm down. Your rights are not being violated.
