I have wondered that as well. Are the police allowed to release the recording of a 9's call without permission of the caller?
I do know that the police get some crazy emergency calls so I wouldn't rule this out completely.
We had the same discussion about is it theft if the snowman was left on common ground at work when the story was told. We didn't come to any conclusion. My friend was slightly miffed though, him and his son had put alot of effort into building it and was then deprived of being able to look at it.
