another COP of coffee

I was on the road today and at a stop light there were seven cop cars. They were on the shoulder and I first thought they had pulled over some arch-nemesis to society, but ... there was no other car. There were only officers. A car headed in the opposite direction while I waited at the light and illegally did a U-turn to join the others.

Uh, perhaps not so coincidentally, there was a Higher Grounds Coffee shop on the corner with PLENTY of parking in the lot. Why don't we call more officers to the scene? Wasn't there traffic to direct or robbery to prevent?
