For once I can agree with jgoins, but it's not just the government in the US that is ineffectual at solving real problems. Given the number of guns already in the US any sort of ban on ownership will most likely push many of those guns onto the black market and into the hands of criminals, or at least those prepared to defy such a ban.

Part of the discussion on how to prevent these mass killings has to be around the tools used though. The simple truth is that the majority of mass killings in the US are done with firearms, not with cars, knives, or any other tool you want to use as an example. There are reasons for this. My guess is that it's because firearms are effective at doing what they are designed for, relatively easy to obtain and relatively cheap.

Banning firearms in the US will both not work, and not be accepted, so are there other things that can be done that will work and be accepted? I know jg thinks open carry is the answer. I don't, but thankfully it is not my decision, nor his alone, to make.
