Um its called government programs.
Illegalize handguns and assault weapons. Create programs to get the weapons off the streets like the ones used in Canada (trade in your gun for money from the government).

You guys act like there is no way to get rid of guns in America... that's such a negative attitude. Guns are a means to easily create needless deaths PERIOD. So get rid of them. Guns create an illusion of protection and safety when in actual fact it's just a domino effect of criminals needing guns to cause crime.
Think about it, if you were going to rob a house and knew the homeowner had a gun, don't you think you would bring a gun too? Why do you think most home robberies never end in death in Canada, because no one has a gun, criminals have no reason to take that extra step because its unnecessary.
The father that killed his wife in this news post was not a criminal, he just had the means to create the crime easily available to him, and since he was obviously angry and not in a sensible frame of mind he inflicted as much damage as was available to him. If there was no weapon then this wouldn't be on the news because he probably would of tried to beat her to death which would give the woman a lot better chance of escaping or survival.
You want some actual facts and research done to prove that Gun Availability is directly associated with Murder and that Gun Control Laws actually lower the Murder Rate, then look here:

The problem is with you people is that you don't do the research before opening your mouths on a forum or making stupid decisions.
