Gun control is not the same thing as gun violence. Today, in the US, we have over 20,000 active gun control laws on the books and there isn't a single one of them that will prevent the next gun-related crime.
Humans tend to be violent, at times and, when they have one of those times, they will grab anything they can use as a weapon. If we outlaw private gun ownership, it will be knives, baseball bats, bows and arrows, big chunks of wood, large rocks or pieces of concrete . . . . When someone is angry enough to attempt to kill another, ANY item can become a lethal weapon. If they ban guns, where will the bans ultimately stop??
Laws are created to control law abiding citizens. Criminals are also called "outlaws" because they they don't comply with the law. So, this is a continued attack on our freedoms by leftists who 1) hate the Constiution, 2) hate freedom for anyone but themselves and 3) want more control over the rest of us. Right now, the only thing that separates us from the Egyptians (and Morsi) is that we have a lot of guns and ammo and will (if necessary) use them to fend off any attempt to destroy our Second Amendment right.
Our Founders are currently apoplectic over the corrupt government that our career elected representatives have perverted the system they so carefully and thoughtfully created.
Gun control is kinda like trying to solve drunk driving by making it harder for sober people to own cars.
