Dominican immigrants, probably mostly illegal, I’m guessing, go on a rampage in Pennsylvania, sending one cop to the hospital with a head injury. It all started with a celebration of Dominican independence at a high school (emphasis added):

Acting schools Superintendent Anthony A. Georeno said Wednesday night that students of Dominican descent were involved in a variety of celebrations in the school during the day, including an approved assembly with a speaker.

Georeno said he did not know the name of the speaker nor the topic of his presentation.

Question: Why were celebrations allowed in the school on school time?
