A modest proposal: Gun owners should be subject to the same strict limitations as some people have proposed for Muslims, including profiling, special IDs, surveillance and internment.

All of the mass-murdering attacks, foreign and domestic, have been carried out by people with guns; some gun owners express violent and rebellious ideologies, and current measures have proven insufficient to identify all mass murderers in advance. We must do everything we can to protect our citizens.
