The people who do these things like smashing windows on public transport or any other vehicle either do not realise how serious and traumatic it is for the person on the receiving end due to been so brain dead, or simply don't care either way that the item thrown might hit someone in the head when it goes through the window or the fact that bits of shard broken glass might get into people's eyes and cause blindness.
Utter scum.
This happened to a few passengers a few years ago on a tm travel bus parked at a bus stop in darnall. The bus pulled in at the bus stop and got a lot of windows put through and a elderly lady got covered from head to toe in shards of broken glass.
I don't know what happened to the elderly lady because no one seemed to know back at the depot but I only hope she was ok and didn't have any serious injury's and managed to try and forget about it and carry on as best as she could when or if she was sent home from the hospital. Bless
