Frank it's not irrelevant. Leaving aside the presumption that 14 shots in front of your wife and kids might be deserved, there is still the question over whether or not 'what he got' was a state colluded (and quite possibly conspired) execution with no judicial process, transparency or accountability. It is not irrelevant that a state which claims to act in the interests of its citizens and with their electoral mandate, also colludes and conspires in the extra-judicial killing of those citizens.
If you can't see that relevance, or if you are unable or unwilling to disentangle it from the obvious human horror of a life violently taken, then you are failing to see if not the whole picture than at least a bigger picture.
