Wow, I'm surprised that you actually think riding home in a police car is fun. I know for sure that YOU would not like cleaning up toilet paper in a tree, especially a tall one, which you would need a ladder to get to. Someone could get hurt climbing up that high. So techinally you could be indirectly hurting people. That in my opinion, is really rude of you to do and if you get caught don't complain that you have to clean it up. My dad said if he catches anyone doing this stuff to our house they will be cleaning it up. ;)
I also agree with Vela, she is always right! :)
