As a new arrival to the 17th District, I probably wasn’t the best choice for this assignment. I was assigned to block traffic on Peterson Avenue after a request from the fire department to shut down all traffic while they battled a raging house fire. I quickly arrived at my post and swung the squad across Peterson blocking both Westbound lanes. I stood by my car with flashing blue lights and disposed of the vehicle traffic down the side street. After a few minutes I noticed that the traffic coming out of the side street looked very familiar. I had been sending the cars down the side street that ran into a culd-da-sac and they were returning in full force. Nobody looked very happy.
