The scary part is the cops arrested them - removed them.
What law were they breaking?
They were trespassed.
Doesn’t seem to be any rhyme or reason: if the “owner” doesn’t want you there they simply declare you are trespassing and the cops enforce that.
[In this case, the “owner” is technically the tax payers but the damage is already done by the time the cops apply the law.]
Parents: consider refusing to play that team.
I can tell you which law the cops were breaking...
“Section 242 of Title 18 makes it a crime for a person acting under color of any law to willfully deprive a person of a right or privilege protected by the Constitution or laws of the United States....”
Just the latest example in a long line of disappointments with woketard LEOs crawling out of the woodwork since the summer of love. It's why I took down my back the blue flag and burned it last year. *hock ptooey!*
