I think that in my day I could have been one of those mindless youths, i certainly had school mates who did such mindless things (as opposed to vandalism )this was mostly around building sites ,not sites of historical importance. We lived near the Roman Wall and climbed over it and that was about it. I am not defending their actions ,so I hope that they are found and maybe eventually one or two of them will realise what they have done. I think that they were very lucky that none of them suffered any injuries . 5 mindless kids reflecting our mindless thoughtless society.
