I’ve got a couple of posts now on why you should never talk to the police. One comes from a commenter who proposes a sixth rule of concealed carry, and one is video of a lecture by a law professor.

Another commenter, 1st Lt L diablo, also proposes the following:

And never let them in your casa. Even if they have a warrant; make them break the door down (a former LEO told me that; I’m not kidding).

Seriously. Never even open the door for them; they can use any excuse to invent PC (Probable Cause) from sights, smells, noises they have access to once the door is open. Make them break it down.

I’ve never heard that one, but it also makes sense. The fact of the matter is that if they’re at your door, they’re looking for a reason to arrest somebody. And since it’s your house, it’ll probably be you. Not to be paranoid, but the less you give them to work with, the better.
