Scary. And the responses from some are about how more people should be carrying in public places. As if the gun fails don't matter.
People think that the real world is like a superhero movie where the good guys know exactly what is happening at all times, and the bad guy is easily discernible. (Plus, when the bad guy appears, the music changes so we know it's him.)
In real life, someone fires a gun in a crowded place, people start running and screaming, there are echoes and ricochets, smoke obscures vision and nobody can tell where shots are coming from.
a gunman in a crowded place pulls out a weapon (or a suspected gunman pulls out what someone else thinks looks like a weapon) a whole lot more people can start firing off their guns. I know I would feel safer in public knowing that if anyone pulled out a weapon there would be lots of bullets flying in every direction.
Instead of just one possibly crazy, possibly armed guy for the police to track down, there would be multiple possible assailants, any one of which might be the original shooter. The police who show up at the scene will find dozens of people running around firing guns at each other. They would have no clue whether there is one crazy bad guy being subdued by legally armed patriots defending their liberty, or if there is a gang war going on, or if it is a terrorist attack. Plus, most people with guns are not accurate shots to begin with so nobody will be able to tell who is really trying to shoot someone or what they are aiming at.
Plainclothes police or security folks in pursuit of the bad guy who pull out their
weapons would get shot in the confusion. You know it.
Everyone is safer with more guns around. Right? Right?
