If I am pissed off enough, does that excuse my violent actions.

Re; Baltimore, Ferguson etc. -There seems to be this notion that African Americans can be forgiven for their violence against private property because they are pissed off about something.
And, truth is, they have a legitimate basis for being pissed off in certain circumstances.
But, we can all be pissed off, and we can all imagine that our version of pissed off is better than the other version of pissed off.
But truth is, everybody can be pissed off about something.
So, if anybody out there is really pissed off, does that justify burning down or otherwise destroying private property?”
