Guys on a Truck

On my way to work, I saw a big truck with saw horses to be used for crowd control. There were two guys standing on the truck to keep them there. They weren't strapped in, and even if they were, would they be able to stop all those pieces of heavy wood from falling without getting crushed in the process?

What are they thinking! They should tie them down properly before they get on the road. They probably shouldn't be on the open back of a truck either. Some one should call the cops!

Oh wait...
