I've got this hankerin' to call 911. This law could get repealed mighty quick if it's senators and congressmen getting pulled over from anonymous tips.
I like the logic, but the problem with that logic is that senators/congressmen/judges/state politicians etc usually have special license plates which make it clear that they are 'somebody'. Cops may see that and decide not to kick the hornets nest.
Quark! Quark! Beware the quantum duck!
