Pacifier

No, a gun is much easier to use than a knive. a knive requires physical contact, you have to thrust the blade into the victim while a gun is just a pont and klick interface. There is a "safe" distance between you and your victim.

But I also believe that gun control would not be a good solution, it would only fight the symptoms while the problem, the violence in the american society, has different reasons than just the possession of guns.
