re: If we change gun control, how do we change it?

The problem with all these mass-shootings doesn't lie with guns, the law, or even mental health.

The problem is that we've created several generations of coddled little babies who don't know how to deal with adversity. They are taught that life is "fair" and that there is no such thing as winning or losing (everyone gets a trophy). Make a B in a class? Mommy and Daddy will raise hell until the teacher raises it to an A. They never have to learn from failure and deal with its impact.

Then when they enter the real world and it kicks them in the nuts, they are not equipped to deal with it, so they lash out in irrational ways.

To answer your question...there is no change needed to gun control, unless we simply do away with control altogether. Guns aren't the problem. Pussies are the problem.
