So I pull into the lot, get out of my car and I see a group of 7 idiots. It's 11:30 at night and what are they doing? Playing night basketball/tenis/football in the vacinity of all the cars in the lot! (3 spots away from my car) I saw them nail a few cars with a basketball, don't know if there was any damage. So I run up to my room and call the campus police and tell them what I saw and that they possibly damaged a few cars. Did I do the right thing? Will check on my car in 10 minutes.
