As far as I know, “defacement” of currency is only illegal if the action makes the denomination or serial numbers illegible.
“if they want to stand around on street corners and scream his name like fools, who am I to stop them.”
That’s funny, because no other candidates were doing sign waves this year until the Ron Paul people did it. Now the Fred Thompson people have taken to coming to Ron Paul sign waves here in NH and trying to crash our party.
I have found that Paul supporters seem to consistently ignore laws they don't like such as defacement of currency, internet gambling and smoking pot. The latter is probably where you are picking up most of your younger supporters. IF he gets into office, then you can change the laws to your liking, but until then what you are doing is illegal and I will call you on it. As I said, I will stick to hanging out with a better class of law abiding citizens.
