While I personally do not think words are not a good indicator of actions, that is the assumption security organizations operate under. I am a bit perplexed as to why you would say 'it was just a ...' though.
The Secret Service takes action against what is perceived to be a POTENTIAL threat, not a PROBABLE one. For example, a little old lady who idolizes whoever they are protecting but has a can of mace in her purse is seen as a threat if she wants to greet her idol with said purse in her possesion. Not because she would use it, but because she could. Even if she did not use it herself, someone not of her dispossition could steal it and use it.
So they should arrest everyone who opposes Dubya's policies and send them off to internment camps, just in case? Along with everyone who owns a weapon, and everyone who's ever sung a protest song? There does have to be a limit.
'just a school talent show'?

Limits?
I realize it does sound extreme, but I am stating the facts of how things work, not saying how they SHOULD work.
