On Thursday, a man went into the airport in Houston with firearms and later died of self-inflicted gunshot wounds. It was illegal for him to take these loaded weapons into the premises, and loads of TSA and metal detectors did not prevent him from breaking laws and inflicting harm thusly. Thankfully, he at least chose not to take anyone with him.
Contrast that with the NRA convention in downtown Houston this weekend where legal CHL holders freely carried their own concealed handguns into the venue where there were still thousands more guns of every stripe on display. No one was shot or threatened. People were generally courteous in what could have been a very stressful press of humanity, with its estimated 70,000 or so attendees. Yet not a single shot was fired and no one was threatened or in danger. "An armed society is a polite society."
How does messing with the rights of people who already obey the law make anyone safer from people who are already breaking the laws?
Come to think of it, the most hostile people I observed this weekend were the protestors.
