Also , the US laws have no consideration about who is the cause
of the chain of events , so if as in this case the police would have
told someone to not try to arrest someone and the guy is still
proceding he can be condemned because it would be assumed
that he willfully provoked the death by not following the police instructions.
If I correctly understand the above you are incorrect on at least 2 items.
1. U.S. laws (actually they are state laws over here) DO have consideration about who starts a fight.
Some states do not allow the person who provokes or started the fight to later claim self-defense. Other states allow it, but only under strict and limited circumstances.
Generally, in states that do allow the person who provoked/started the fight to claim self-defense, they must, after starting the fight, make it clear that they want to stop and/or try to retreat. Only if the other person refuses to stop and prevents them from retreating can self-defense be claimed by the person starting the fight. This provision was put into law to allow women to claim self-defense. There were too many cases where a woman started the fight with her husband/boy friend and where, after the (abusive) husband/BF went 'crazy' beating the h3ll out of them, she later used a gun in self-defense but was convicted of murder because self-defense was not permitted as she started it.
FL law states fairly clearly what constitutes "provoking" a fight. Merely following someone is insufficient. It takes an actual physical attack to meet the definition of "provoke" under FL law. IIRC, a serious verbal threat of violence can also qualify.
But merely following someone or merely insulting them, whether it be racial epithet or whatever, does not qualify as "provoking".
