I didn't say anything about right or wrong, just legal and illegal. Serving a no-knock warrant may or may not be wrong, but it is not, in and of itself, illegal. Likewise, I'm pretty sure if you go back and look at the Nuremberg verdicts, you'll find that they were convicted for violating specific laws and treaty terms, not for doing something that was "heinously wrong."The guys on the raid know (or should know) that kicking in a guy's door based on intel gleaned from a crook for a victimless crime, and then shooting him for attempting to exercise his God given right to defend himself from an unknown entity that's breaking down his door is heinously wrong.
