The job of Congress is to pass laws so when you say that violence will continue until Congress stands up to the NRA you are suggesting that new laws are the answer.  I'll ask again what magic law stops yesterday from happening?

Let me help you.  Gun violence is a myth. Guns are inanimate objects. There is only violence and violence is a product of the mind and the mind will use whatever tools it has available at the time. Cain killed his brother with a rock after all.  Do you believe that there is such a thing as rock violence?
