it puts another obstacle in the way. each obstacle helps make these sorts of things more difficult to carry out. i'd have thought that quite obvious.Also as another point @Thekwango how does keeping your gun at a range prohibit the guy doing what he did? If a guy wanted to shoot up a load of people, he can just go to the range, get his gun and do what he wants to do. Location of the gun I don't really think makes much difference, preventing nutters from owning guns is the more pressing issue here.
