Four helicopters

I decided to take a quick walk around the block before dinner last night. I was halfway done when my brother caught up with me. Just about that time, we noticed there were a couple of helicopters in the air. Circling. Hmm. We speculated what the problem was. A few minutes later there were three making a circuit of our neighborhood and beyond. Hmm. By then we had arrived home. We figured two were police helicopters and the other was a news copter. Finally, a fourth copter joined the circuit. A neighbor across the street told us what happened: There was a shooting a few streets away. Pretty sad.
