Seriously doubt it. Things like this happen from time to time. In the past there was always a slight over reaction. If anything Columbine should have started a hardcore ban on fire arms. But it didn't and is won't either. Politicians will be quick to lap up what ever political milk they can get, but most of it will be all talk.
Just like most thing you see on the news, or that happen. Kind of like that policies brutality thing you posted a while back. In every country there are examples of police going overboard. Just cause this one was caught on tape doesn't mean it's the start or evidence of some police state.
