No it does not, the Police can choose if a case should be tried or not, they can and do let people go all the time without charges after said people have killed other people. I believe if someone is killed and the killer claims self defense, no matter the circumstances a trial needs to be held to verify that the self defense was valid. I don't care if 10 witnesses and video tape evidence shows a raving lunatic welding a weapon charging the suspect that then shots the lunatic dead, a trial needs to be held. That list was nice, I particularly find it funny death by fireworks made it on the list at one in every 0.65 million deaths. Does that mean we should outlaw fireworks, no, but we could reduce death and injuries by fireworks by requiring that only say adults can by them and limit their explosive potential, even though these deaths are truly minuscule I see no reason why practical safety measure should be ignore. Likewise with guns as 9th most common cause of death and *only* killing one out of every 321 Americans I see no reason why we can't have more gun restriction and safety laws. We put seat belts in cars, require car insurance, car inspection, etc, etc and it kills people 3-4 times more then guns, meaning it would be prudent to put some restrictions on guns.
