so if you're going to ban guns so people don't kill people you my as well cut everyones fist off, ban knives, ban hamemrs, well ban basically everything.
No - here is the real issure: guns have only one use, kill things; fists, knives, hammers, well everything all have a main function/use that does not include killing things. So if we are going to talk about banning things (and we are not, we are actually talking about regulating - as in 'well-regulated') we only need to ban something whose only purpose is to kill things.
You honestly think if everyone had a gun on them at all times crime will increase?
We actually can look to a time in history where everyone who wanted to could carry a gun - the time between the end of the civil war and the beginning of WWI in the US. Everyone in the West could carry a gun if they wanted to and so what happened can be followed by researching the Earps and their attempts at law enforcement. The Cowboys ran roughshod over everyone, even those who had guns because they had more guns. I am not going to go over the entire story here because it is a story that ran to its inevitable end in every town in the west. Guns were outlawed in town - this is how the west was won. It is true in Tombstone, Virginia City, Deadwood, Hanging Rock, Cody, everywhere.
