Somehow I doubt people are being arrested purely for protesting... They'd obviously have to be starting trouble, trying to incite a riot, or whatever. Besides, most people arrested at such places are maybe kept over night and then released.

It's not as if all voices of opposition are being stifled, taken outside and shot... oh yeah, that was Saddam. lol

Don't get me wrong, I'm not "for" this war... Personally, I'm tired of the USA trying to serve as the world's baby-sitter. :p
