And once again fingerlakes, you are proving your ignorance about guns and so called "assault weapons." You sound like someone who has never shot a weapon from your ignorance on the subject, or you're just too stupid to do actual research on guns, but either way, you don't know the definition of an assault weapon and have probably never shot one before. Just because a gun "looks" scary, doesn't mean it's as powerful as you think. Do some research before you post about something you know nothing about.
Here's a picture to make it a little easier for you to understand. Most murders caused by a firearm are by handguns, not assault rifles.

These laws are going to do nothing and I can't wait to see who you people blame when it happens again, because it will. Criminals aren't going to abide by all of these new "laws" and will find a way to get guns no matter what.
"How about ensuring that you keep them locked up?"
And how are they going to do that? Are they going to go into every gun owners home and check to see if their guns are locked up? That doesn't seem very constitutional.
