I used to work at a Business in Squirrelhill and we had a huge issue with large groups of teenagers coming in and trashing the place and the bathrooms. We had a rule that no more than two teenagers could be inside at one time. Once there was a couple kids with a basketball that were bouncing it against the window and later I learned they had stolen the basketball from the JCC and it was apparently a chronic issue. I also saw a kid open up the gas cap on the bus and throw some thing inside. There were literally groups of teenagers roaming the streets repeatedly up and down Murray Avenue and yelling and hitting people. That was one of the main reasons I quit that job.
