Ban guns. All guns. Get rid of guns in homes, and on the streets, and, as much as possible, on police. Not just because of San Bernardino, or whichever mass shooting may pop up next, but also not not because of those. Don’t sort the population into those who might do something evil or foolish or self-destructive with a gun and those who surely will not. As if this could be known—as if it could be assessed without massively violating civil liberties and stigmatizing the mentally ill. Ban guns! Not just gun violence. Not just certain guns. Not just already-technically-illegal guns. All of them.
Don’t ever let anyone get away with telling you than no one wants to take your guns.
There is no political hope for these anti-gun people to accomplish their goals. There is no culture support for their goals. In fact it is just the opposite. Support for the right to keep and bear arms has not been stronger in decades and these people know that. When certain conditions are all met people who are absolutely, without any doubt, proven wrong their reaction is to increase proselyting their failed beliefs. Those conditions have been met and we are now seeing that increased proselyting. Read the book.
