In those several states with open carry what is the crime rate? Compare that to a city with high gun restrictions like Chicago(murder capital of the world).Yes, the gun is an inaminate object, but one that some folks can use to kill 20 innocent helpless children aged 4 to 10.
If this inaminate object in the hands of the wrong mind can end the lives of others, then its possession requires control.
Even healthy minds might, for a second, become disturbed by some traumatic or distressing event, and the inaminate object is perhaps too handy for this momentarily disturbed mind to do something completely out of character. It only takes anger or whatever. And some person is dead.
How do you measure the disturbed mind, especially if it appears for only short times, which may not be noticed by anyone? Life, once gone, is not recoverable. A dead person remains dead. How do you keep life safe and sacred? How do you safeguard against harmful use of the inaminate object?
In several US states now it is legal for gunowners to carry and display handguns openly while out and about, shopping, having a drink at the local bar, etc. How safe do folks feel in a bar at night with a crowd of gun-toting drinkers, perhaps some with their mental processes impaired and their irrational emotional responses loosened? Does this reveal the fact that the USA has not out-grown its wild west history?
You don't have home invasions in Texas, people own guns. Chicago, you cant legally own a gun unless you jump through 500 flamming hoops. Yet its murder capital of the world because criminals don't care what the law says, they'll carry a gun anyway.
You are just taking guns away from law abiding people, only thugs and criminals will have guns. And these law abiding people won't have anything to defend themselves with.
Lots of open carry places in the USA and no shootings.
