He couldn't get his attention without shoving him to the ground? The only person putting his family in danger in this situation was himself.
It's why I won't fight guys for making comments about a girl I'm with. It's taking a bad situation, and turning it into a violent one.
Now if they are putting hands on her, that is completely different and I would risk my life to protect hers.
It doesn't matter if he was right or wrong for pushing the guy. The point is that the push doesn't justify the shooting. If McGlockton really wanted to harm Drejka seriously, he would have followed him to the ground and started dropping bombs before Drejka could even get his gun out. He clearly wasn't interested in further unprovoked physical contact. If the police were there, McGlockton would have been charged with simple battery at worst. No jail time. Maybe a fine and/or community service/anger management would be the likely punishment. There is no way that reasonably meets the standard for being "in fear for you life". You're telling me that this guy is such a pussy that merely being pushed invokes serious fear of death but he is somehow brave enough to confront people over parking? Sounds more like a gun owner who goes around looking for reasons to use his gun.
