I understand what you're saying, but in a universe where you will be casually killed for a parking violation - I have the feeling that ship has already sailed, hit an iceberg, and has been residing at the bottom of the ocean for quite some time now.
Taken from my other comments:
There are situations you have to neutralize threat. That is why cops have tasers, stun batons, pepper spray etc.
Generally you always want criminals to be taken alive to be able to question them! Think!
There are exponentially more reasons not to kill than to kill a person outright. So giving only one option - killing - feels wrong and forced.
What sane people do facing unfair world? They do all they can to make it better! Staying human instead of degrading to animal means advancing, progressing, becoming better, even if we have to pass trough some bad times.
We don't go pardoning SS members for massacres because they existed in reality.
Plus Elite universe is diverse, from monarchists to communists, from poor agri-worlds or plague-worlds to futuristic paradise planets.
