Frankly, it doesn’t pay to try to correct bad behavior on your own. The marines should’ve probably just called the police & let them deal with it. If they didn’t come, let the kids do what they do. The world we live in...
The marines should have left if the fireworks offended them. Kind of a Karen thing to do unless someone was getting hurt by said fireworks.
That being said to be attacked by a mob that large is disgusting and it’s unfortunate the marines were not allowed to be armed
