i believe the us judicial system is a lot more effective than here in england, there people actually get lengthy sentences, rather than less than half the time that they deserve because our prisons are too full like they are here. its not your sentencing that is wrong, its the way that firearms are too easily obtained! the reason someone with a conceal/carry permit is not likely to commit an illegal shooting, is becasue they obviously have a very good reason to be carrying a firearm-work/private security etc.
i stand by my previous statement, you have not seen the last high school/college massacre, not by a long way, anyone who thinks otherwise is kidding themself. somethign must be done to stop firearms, especially handguns, falling in to the hands of these people. until that happens, well, it only a matter of time until it happens again.
