Well it's true that France doesn't need to pass their own patriot act tomorrow and start restricting freedoms, under reacting is also possible. The fact is they were attacked and a response is necessary. It doesn't need to be reactionary, it can be thoughtful and measured, but something needs to be done.

I don't think anyone is saying that there should be no response, people just think we shouldn't over react. Closing off the borders and refusing to take more Middle Eastern refugees is a sane response, starting more wars is an insane response.
