Well done
Even though you were not positive of the regulations, you took the pictures and did some research, made the call. There are many in this world that claim nothing will be done etc., but YOU did something. I am often puzzled by the attitude that because the law is not going to do anything, we should just ignore it. From personal experience, even though the "law" may not always be able to "bring them to justice", the victims are thankful. We are all vicitms when it comes to these sorts of crimes......so THANK YOU!!
