I kind of disagree, with current nanny state the shooter is guilty and will most likely go to prison.
However ... you got two dudes with clear beef and I don't see why that didn't have to be resolved. Teal shirt called other dude's bluff and wanted to play the game, well he won a prize.
Was this a frontier town or most any other place before bullshit laws, teal shirt should have known to keep his mouth shut. He was asked to leave, right or wrong. If he wanted to play a game, he needed to bring something else than a check his ass could not of cashed. This is a perfect example of cucked society that relies on nanny state to sort shit out of them. You want to know why we have "gun laws" despite 2a ... this is why, people beg .gov to arbiter their shit for them.
Meh, they were preventing a dad from seeing his kid, I’m pretty sure that’s grounds to be upset. This is more what happens when pussies resort to guns as a first resort and not a last.
