We need guns that do not kill, that's all.
Hoping in technology to bring a social change soon. everyone should be able to protect themself, yes. but the way it is right now makes killing too easy. imho even the police should use paralizers and not guns, at this point. this would give to the people the time at least to see if the person was guilty or not. it's not just about the person (even if I do believe life matters a lot), it's about who has the gun: you may regret too much what you did (maybe you were actually wrong even if the situation was insane) and no one should live with the guilt of 'I killed someone but I was just trying to be safe' when there are so many other options. the actual sistem is incredibly old-world, western-situation.
