Policing Issue

For telling unsupervised children to stop defacing property you almost get arrested. What is wrong with this picture? We just had the flagpole and monument put in last week. A new fence today, but this is what we have to clean up and get harassed in the process. The dedication is Saturday and the smell wont even be gone by then. It is a sad city that I live in. I am no longer a proud New Haven resident
