The dumb robber

One day I was in health class and a police officer came in to teach us something but we started to ask about some of his cases as a cop and a kid asked him what was the dumbest case you ever had and he responded with this.

There was a place they were doing construction on and the robber diceded to cut a hole in the top of the building and stranded in the middle so he fell in and all of it landed on top of him so he was stuck.   That was a mistake cause he heard a noise and went to the building and the robber said " Help!" said the robber. The cop " Who is there." he said. "It's me the robber!"
