First of all, they weren't police. If you see somebody in front of you with a shotgun you may not just want to put up your hands like they are legitimate authorities. You may not want to give them the legitimacy that they don't have and don't deserve.
Secondly, he may not have "wanted the shotgun." He just didn't want the other guy to be able to use it on him. The idea that the killer was afraid for his life misses the point that the killed man was that much more in fear of his life and had more reason to feel that way.
What the victim did wasn't wise, but people don't always react in wise ways when under stress. Plus, if you've been running for a while you're apt to have more hormonal energy than brain sense.
Before we draw comparisons between what happened in Georgia and what happened in Delaware take into account that this is some months after the Georgia incident happened. It wasn't this big a story when it actually happened as it is now, and the Georgia authorities probably didn't say more or move faster in the beginning than the Delaware authorities are now.
I will always and forever think grabbing a shotgun, without knowing it is loaded but the thing was pointed so odds are...I will always think that a stupid thing to do.
It does seem like this guy was...well I dunno, I kinda think he was snooping around that house under construction for no good reason but I ain’t the cops but I got a right to my thoughts.
But he didn’t have a gun and what the hell those yahoos with a loaded shotgun were doing out and about defies reason. Were they planning on shooting someone?
But he grabs a loaded gun already pointed at him and it goes off and now he’s dead. I’d like to say I would have put up my hands or begged for time and explanation but like you say, adrenaline sometimes is in control.
I am not convinced this guy was oh so innocent but he didn’t deserve to be shot and those who shot him should be punished.
I’m done discussing.
