Why?

I came across this mess whilst out buying mower fuel this morning.

It's obviously been destroyed last (Saturday) night.

I must have led a sheltered life, because there's no way I can understand why anyone would do this. It can't have been easy, probably involved a number of people, and I'd be surprised if bodily injury wasn't occasioned in the process.

Perhaps whoever was responsible used his/her head.

No damage would result to a head belonging to someone thick enough to do this.
