Absolutely 100% BS. Paddock did not "misuse" the guns in his possession. I am a gun owner and I have no problem being honest about guns. They are designed and built for one purpose, to KILL.
I have weapons for two reasons: to kill animals for food, or to kill humans who endanger my family.

When you add things like bump stocks, or other modifications to effectively turn a weapon into an automatic, the gun has only one purpose: to kill mass quantities of people. Paddock used his guns EXACTLY for their intended purpose.
