Go police!! I would say the same thing if it was my own kid. A neighbor once called me saying my kid was setting off firecracker in the wooded area by our subdivision and she said she was going to call the police on them (several boys) and I said "ok". Dumbfounded her! They only did a couple and quit and he got yelled at by me. My opinion is if you are doing something wrong and you get caught it's your own fault, no matter the age.
