Yeah, the cop crossed the line. But the "fact" you state are from one of the crowd that crashed this pool. The other side of the story is that this group continues to crash pool parties across the area led by a guy on Twitter announcing places and times along with spots to hide from cops when they show up. There are also eye-witness reports of some of them having sex in the pool. They were asked to leave and didn't. Fights broke out.
Still lots to learn about this incident. Don't take Huffpost's lame article as "facts."
“But the “fact” you state are from one of the crowd that crashed this pool.”
It was an end of school party and it’s in a link someone else posted. The kids live in some rental properties in that neighborhood and sent an invitation via social media.
you are correct, lots more to this story.
