I think they want to appear to do something, they are of the mindset, "well, we need to do something, anything" so they can say, as Feinstein did today, "Well, I gave it my best shot", nobody says anything about actually making sure it will be enforced, or if it will actually prevent shootings, it won't, they know this thats why they are waiting till the next tragedy to happen so they can pass more laws, more restrictive laws.
