"Elliott allegedly tried to wake Avalos by nudging him with the pushcart"
That's not asking someone to move, that's using force to try to get them to move. Although I agree public property means we should all be able to use it and no one should block it, I disagree that any individual is allowed to use force to enforce that law. Report such lawbreaking to the authorities, and then simply walk around them.
it would have been perfectly justifiable to respond to a flying shoe with an ass kicking or better yet pepper spraying
After Elliot assaulted Avalos with his cart, Avalos yelled at him. After Avalos yelled at him, Elliot pulled out his gun. After Elliot pulled out his gun, Avalos threw his shoe.
If someone pulled a gun on you after you yelled at them, would you be justified in kicking their ass or pepper spraying them?
The only thing I understood, based on the murderer’s choices, was that he started a confrontation he could have easily avoided, and then chose to kill someone instead of disengage. I would never kill someone for blocking a sidewalk or even throwing a shoe at me. Neither of those things are life threatening.
Why he decided to assault someone with his pushcart, I also don’t comprehend. Just walk around the person. The only thing that makes sense is this murderer had intent to start trouble. It’s like Markeis McGlockton‘s murderer. Some people go around looking for a fight, it’s bad enough that they get away with this most of the time, it’s worse that they are able to carry around a gun. This guy needs to spend the rest of his life in jail so he doesn’t shoot another person just because he’s pissed off.
