propole hundreds are killed on the roads every year but the government doesnt ban cars ,instead it encourages the safe use of them , yes that ladder is a big one but if set on level ground it is not windy and the operator feels safe using it then leave him alone otherwise we will start banning everything from horse riding ,skiing ,formula one motorbikes and the list goes on. i agrree that it isnt right to force someone to use that ladder and if they or you didnt want to then that is your right but that doesnt alter the fact that what he was doing was no more dangerous than many other activities taken for granted
