We’re not the DA so we don’t have all the facts. Which leaves speculation for many issues. Borrowing your format:
Fact: Reeves knowingly entered the theater armed with a gun in violation of the establishment’s ‘No guns’ policy.
Reeves was willing to violate one theater rule in order to enforce another? Or did he just intend to kill a texter, which was ultimately a veteran and father of a 3 year old girl?
If Reeves’ Deputy son was also coming to the showing it cannot be asserted that he was armed for self-defense. That’s means he was carrying the gun into a ‘no gun’ establishment with the intent to kill. The shooting was pre-meditated. He should have been charged with 1st degree murder.
So many things are going against Reeves living much longer. In particular the widow’s lawyers. She doesn’t need lawyers for Reeves prosecution but for a civil suit against him and his estate. I won’t be be surprised in the least if Reeves is extended a professional courtesy this weekend and he’s found to have taken his own life.
I would be willing to entertain your speculation about free LEO movie tickets before jumping the shark into premeditated murder because the shooter's LEO son was going to join his parents at the theater.
You have a remarkably colorful and detailed imagination! Have you considered writing novels? Are you already published in the fiction department? Do tell!
