Seems this one was a British export.
I'd be more than willing to listen to a plan that guarantee guns would likely not get into the hands of this kind of person. It makes little sense to make laws with no teeth and/or are selectively enforced. We have created an environment that doesn't allow for action until after a criminal act has been committed and the perp goes through a very generous process of law that favors him rather than the victim. Until we correct the leaks in our legal system, there's not much sense in believing new laws will cause criminal behavior to slow.
