That's basically the whole basis behind so many laws and regulations passed lately. Government of course usually wants more power, so of course it'll exploit any incident or tragedy to show it's "doing something" rather than simply stating "You know people, there's only so much government can do."It gives the people the impression that government is "doing something", and that makes people feel better, even if it's ultimately to their own detriment.
That's a problematic mentality we have today; that it's government's job to fix all our problems. It's usually better if the primary problem solvers are local communities and private sector actors. Government's main goal should be to help supplement those efforts, but not be the actual primary actor.
