I almost got hit with a charge for about this same thing, only I didn't get anything from the roll off. The cops said just my presence on the site was trespassing and anything in my truck was attempted theft. I had to go the land owners the next day and argue that no real containers for the demolition debris equaled no rights to possession and that putting the metal out in the open on public use and abandoned land and not putting up "No Trespassing" or cordoning off the area meant it was free game. Basically these fools just abandoned a gas station that was located in a public strip mall parking lot for 7 years. Now some 7 yrs. later they came back to demolish it and hopefully scrap it. The whole thing was nuts and I couldn't believe our stupid ass cops wanted to hit me with two D felonies over it. Eventually, they agreed not to press charges after everyone got tired of scratching their heads over the situation. Bottom line, if it's demolition, you should definitely ask LOL.
