Are three cop cars enough?

Sirens and blue lights right outside my apartment--curious, I take a peek. OK, so I'm nosy. At any rate, outside are three cop cars, lights flashing stridently. What was the cause of all this display? Two teenaged boys, possibly one of them Latino, although its hard to tell in the dark. The boys are dressed in the de rigeur teen uniform of T-shirt 4 sizes too big, jeans so baggy that the crotch is down by the knees, oversized baggy jacket, and wide white headbands. Perhaps its the fashion police?

The boys don't appear to be offering any resistance--they are just standing there, hands uncuffed, and are certainly making no attempt to escape. Why the need for massive police display? Perhaps its just a case of bored small town cops looking for something to do on a Tuesday night, but I would think a single car with its two officers should be able to handle whatever the job was.
