The trouble with your belief is just that, it is your interpretation of the Fifth Amendment. See how the courts feel about that if you ever get a chance to test it out. I don't see the right to eliminate evidence covered by "nor shall be compelled in any criminal case to be a witness against himself,"
But then again, if you exercise your "right to eliminate or obfuscate evidence" you wouldn't be in court in the first place, seeing how there would be no evidence of a crime.
The suspects have to come out sometime. Make the arrest in the Piggly Wiggly parking lot, read them the warrant on the spot, and the send the search team to the (empty and unsanitized) house.
See above.
Yep.
Thing about it is, in this country, if enough people who have the same viewpoint get together, stuff gets changed.
For an example of this, see the the title of this thread.
