This is such a bullshit reason: For one, you could detect these no-knocking individuals quite easily: - Cameras on the exterior of the property - Motion lights, motion sensors, motion bells are all quite cheap. And re: destruction/obfuscation of electronic evidence- -"One-click" destruction scripts, etc. - TrueCrypt volumes, everywhere. Circuit breakers, power strips, etc. with switches. If you don't manage to destroy the volume, no aggressor will be able to access it. - Degaussing setups for spinning disks, activated by similar mechanisms. This stuff is pretty cheap, easily available. Anybody caught by these technically-incompetent police executing no-knock raids deserves to be caught. Hell, if you don't have a few 6TB volumes full of random bits, labeled "Evidence," you aren't doing it right. Gotta tie up those investigative resources somehow.
