He was on the property to pick up his kid at a court ordered time of 3:15PM, the mother delayed that.
He was told to leave WITHOUT his kid
... so not only did he have permission, that permission was court ordered.
The first to get physical/threatening was the step dad brandishing the gun.
"Stand your ground" works BOTH ways.
Mom AND step dad are going to jail
... it is unfortunate the guy that got shot was named Chad. The step dad should have been Chad.
... and
"stand your ground" is NOT a US federal thing, it is by state law... and is ridiculous cowboy mentality.
... and "stand your ground" says you don't HAVE to retreat. It does NOT allow you to brandish a weapon without a threat (Chad was going to lengths NOT to be threatening... I think he had been in this situation before, his new wife was videoing).
