> proportionality that's the bullshit part, if you're attempting to disengage yet someone attacks you, you should be free to kill them. proportionality is just how slimy lawyers and judges exploit the ignorance of the jury to get you behind bars for self-defence. any attack is potentially lethal and you shouldn't be forced to wait until it's too late before being able to take appropriate measures. a simple punch that connects just right can be lethal, as can the subsequent fall and head impacting the pavement.  basically, fuck the future, you're likely being attacked by a 70iq subhuman who cannot even perceive things more than 5 seconds in the future, if you're worrying about laws and the future trial you will hesitate and get yourself killed or maimed for life. blast his brains out the moment he makes it clear your defusing and disengaging isn't going to work, worry about what happens after later. would you rather be in prison for murder, or be stuck in a wheelchair drooling for the rest of your life (or dead)?
