...to make the tiny handful used in drunk-driving collisions or as escape vehicles easier to catch. Or proposing making the seats uncomfortable and difficult to adjust because we don't want escaping felons to have an easy time of driving away from the cops.
There is a denial of vulnerability that exists here. We, as a people, are routinely in geographical situations where we are horribly, horribly vulnerable to death or injury in the event of a random homicide event, whether it be a shooter, a stabber, or a guy with a bomb. Avenues of escape can be limited even to the fleet-of-foot; the disabled due to injury, illness, or age are even more vulnerable. Police response is an average of several minutes away. Despite the clutching of pearls of some, there is unlikely to be a person carrying concealed in the immediate vicinity. And a person carrying concealed who is perhaps in the area but outside of the immediate vicinity is likely to run away as well; they carry for PERSONAL protection. One side in this argument both mocks CCWers for having Rambo mentalities AND for not running into danger.
So what efforts can (again) be proposed to stop the carnage? The guy had a rifle and several pistols; assuming that rifle was an AR-type rifle and had been banned and confiscated, how would that have lowered the body count when a) there were several pistols available and b) other rifles and shotguns could have been substituted?
What effect would a magazine limit have when the shooter has several guns and a generally helpless, trapped population of victims?
The perp bought the guns legally, so background checks were in effect.
There exists no hardware-based solution for this situation. None. Unless you're going to try to knock the clock back to 1850. If he had burst in there with a lever-action rifle and a trio of six-shooters, we'd have just as many dead people. Ten rounds of .44 Mag in the rifle, and 18 rounds in the handguns. All before reloading. That's plenty of kill 9 people trapped in a classroom.
