"Congress shall make no law...abridging...the right of the people to peaceably assemble...
Suppose you were having a gathering of like-minded individuals to discuss politics in the 30 days before an election in violation of McCain/Fiengold campaign finance laws. If the driver's license or money or passport or anything you are required to carry has an RFID tag in it that identifies you directly, the government can know you were there and then use that information against you. If they have no way of knowing the movements of people in a free society without tagging us, we retain the right of the people to peaceably assemble.
Maybe a bit of a stretch, but indicative of the possibilities on that slippery slope we head down.
SW you're over-reacting.
The McCain-Fiengold Bill does'nt prohibit assembly...it has nothing to do with lawful assembly.
So you are sending up a "Straw Man", presumably to promote confusion and undue concern over ridiculous hypothetical circumstances.
Overstating the "Enormous Threat To Individual Liberty" is a deliberate attempt to "Poison the Well".
These aren't conservative tactics, they are easily left-wing in nature and intended to undermine confidence in our leadership.
