So let me get this straight...
You have an open public meeting to talk about derailing military recruiting, and are shocked when the Feds show up?
You throw out your trash, but are shocked when some of it goes to Uncle Sam instead of that trash-diggin collie next door?
The ironic thing about these activists is that they are not fulfilled... happy, if you will... unless they are getting arrested, drug into court, sprayed with water hoses, etc. If they simply protested while people waved at them then they'd come home, light up some weed, and talk about how they weren't doing anything meaningful.
They love to be miscreants. It's their goal in life.
