anyway the OP, no, i don't think he's going to face any federal charges.
yes the families of the dead men will try to get some restitution and sense of justice in civil courts.
equally someone will probably convince the kid shooter to sue someone for defamation. maybe all that will offset.
and then eventually he'll become governor of some red state. lol ((??))
run on his 15 min of fame & NRA funding. which kinda makes him a shoe-in.
and overall, IMO, my thoughts are that he had no business being there. he manufactured the situation in which he defended himself. i think he should have been found innocent in terms of self-defense but guilty of reckless endangerment, but of course, i am no legal expert.
regardless of what our secular laws have decide - and i understand they decided rightly according to our secular law - he did not receive from our courts, true justice. he isn't innocent in the matter, and this isn't something to celebrate. it points to flaws in the human system of justice as compared to actual divine justice, and it's a pretty big shame that it's politicized because this is a teachable moment for all of us that's sailing over most of our heads.
