I don't agree with a lot of what these protestors stand for. I think they're wrong on a lot of issues.
Their methods sucked, they weren't there using unadulterated wreckless violence to make their point, they got their asses beat by the cops.
But you know what?
At least they were out there exercising their 1st Amendment right despite H.R. 347.
When thousands of protesters are expected to descend on Chicago this spring for the 2012 G8 and NATO summits, they will also be approaching the grounds of a National Special Security Event. That means disruptive activity, to whichever court has to consider it, will be a federal offense under the act. (H.R. 347) [source]
