Oh, those knuckleheads

It’s just a pity that a few knuckleheads have to play the fool and ruin it for everybody:

A recent string of robberies on BART trains took a frightening turn when dozens of juveniles swarmed an Oakland station over the weekend and commandeered a train car, forcing passengers to hand over bags and cell phones and leaving at least two with head injuries, witnesses told the transit agency.

The incident — the first of its kind in recent memory — occurred around 9:30 p.m. Saturday at Coliseum Station.

According to a police officials, witnesses said 40 to 60 juveniles flooded the station, jumped the fare gates and rushed to the second-story train platform. Some of the robbers apparently held open the doors of a Dublin-bound train car while others streamed inside, confronting and robbing and in some cases beating riders.

The juveniles “committed multiple strong-arm robberies of bags and cell phones,” said a police summary prepared after the incident. “At least two victims suffered head/facial injuries requiring medical attention.”

Remember, diversity is our strength. It’s very, very important not to stop telling yourself that. Also, slavery.
