Re: Gun ownership.
Perhaps all the gun toting criminals in Chicago bought their guns in Vermont? Or just stole them.
A criminal is hardly going to use a gun which they bought and registered in their own name are they?
Having different rules on ownership in different states / cities doesn't work unless you have airport-style controls on all the borders - something that would be near impossible to implement.
However if handgun ownership were made illegal (or tightly controlled - e.g. they have to be stored at the gun club and only used there) nationwide then this reduces the available guns for the scum to steal and use illegally.
Gun Ownership is NOT a deterrent, if a burglar is in a neighbourhood where he knows 9/10 of the house owners are armed, he'll just arm himself and go in anyway, and the house owner is that much more likely to be killed.
In a country where there are (virtually) no guns, if a burglar is disturbed he will run. In a country with guns - he'll shoot first to make sure HE doesn't get shot - it's simple.
Take a look at the Firearm Related Death rate and compare the US to England / Wales. There's a reason for the rate being 10 Times higher in the US - and its the availability of weapons.
Having said all that it's pointless arguing the point - Americans are addicted to guns, and there's nothing anyone can do to reverse that - unless someone invents a star trek style stun gun (not a stupid 1-2 shot Tazer), THEN it will be interesting to see what excuse they can come up with to keep them.
