Knives are a deadly weapon too.

Don't forget killer SUVs.

The problem isn't the guns. The problem is with the stupid A holes that have zero value for human life that won't think twice about shooting someone over something stupid. Like wanting a jersey, a pair of sneakers, someone's phone or car, or as happened in my area a few years ago, a person got shot because they stepped on someone's foot in a crowd of people leaving a movie theater.
And then these A holes walk away laughing while their victim lies dying on the sidewalk knowing they will never be punished, especially if they are under age. That is the real problem which this article made zero mention of. Why didn't they mention it? I think we know.
