Well, that's irrelevant.
How is the government going to makes knives safer, or fists, or rope, or any of the other 'weapons' used to kill people in about 70 percent of the homicides each year, your goal is to save lives right?
How about we consider that before we punish the tiny portion of legal gun owners who commit murders, and yea it is tiny, of all firearms used in murders registered long guns made up about 2 percent. You can be sure that most of the handguns weren't legal, and keeping them out of the hands of those who are overwhelmingly law abiding (statistically more likely than you to be so) isn't going to change that.
So you can bleat all you like about this issue, you are wrong on the facts, choose to play the social engineering card if you wish, it is immoral, but that's progressiveness i suppose.
A car is only needs to be safer when you hit something you shouldn't have, after which the state may choose to punish you, or you might get sued. You want to presume that someone with a firearm license is a murderer waiting to happen when in fact they are less likely to be violent than you are. There is a difference. Far more people are killed by the outright misuse of a car by a licensed driver than by a licensed firearms owner. I suppose we need gps tracking on all cars with auto shutdowns for speeding and breathalyzer interlocks on every car, some kind of system that detects when you're distracted or tired and reports you, or maybe just a giant impound lot where you will have to check it out when you want to use it. Do you want to save lives or not?
So, do we need a central chef knife storage now, more people stabbed to death last year than shot, more violence committed with a knife, most shootings not committed with legal guns..so, which is it, do you want to save lives or play games? O, nvm, i see you over there in the sand box.
