So, Gaerek, how would you feel if your car were stolen
Cars are not designed to kill. It is not their main purpose. Guns are.
Furthermore, if I'd left my car unlocked, i.e. not taken all the measures at my disposal to prevent its theft, and someone was subsequently killed in a high-speed collision, then yes, I would feel partly responsible.
I would have been able to do more, and it would have been easy to do it.
When the right to effective self-defence is denied, that right to self-defence which remains is essentially symbolic.
Freedom: Please enjoy responsibly.
Karma. Another word for revolver: because what goes around, comes around!
