Just to question the reporting of the story - how does a felon have 'legal' guns? Not judging - I got a pretty extensive record myself, but that part just doesn't make sense. Possession of a firearm for a felon can bring 5 years alone. Did something change or is this just crappy reporting?
p.s. as far as the story, if true, if this is not a perfectly legitimate case of self-defense I don't know what is (regardless what the gun laws are)
p.s.2. the cop is not necessarily at fault either - just following procedure, if any single person can be pointed out as responsible it's the judge..
