I have a different perspective on this. To me, it's a dick-measuring contest where the "authorities" are putting Joe Q. Citizen in his place for daring to point a marker at them. It doesn't feel terribly different from what the cops do to citizens who videotape their conduct during protests--beat them silly.
The TSA, TIA program, Echelon, [Fatherland | Motherland | Homeland] Security Department, pervasive surveillance, and many other recent erosions of our freedoms have set this country on a swift tilt to totalitarianism. Note: I didn't say "Obama" or "Bush" or any other partisan attribution because it's a bipartisan effort on behalf of the government and those who control it to keep the rest of us down.
Unless those aforementioned parties straighten out and fly right in a hot hurry, I suspect they will soon long for the days when the only things being pointed at them were laser pointers and cameras.
Yes, yes, the U.S. government outguns any amount of rednecks with rifles, but the rednecks and other less-than-red necks outnumber the entire armed members of the U.S. government by orders of magnitude, and the number of soldiers willing to drop napalm on suburban Houston, though still greater than we would hope, is still far less than the government would like to pretend.
