About the guys hanging off the scaffolding....
A friend of mine was on a school trip to Christchurch cathedral in NZ when he was about ten years old. Whilst they were standing in the main square, a suicidal man jumped from the top of the cathedral. The jumper died, but he also hit one of the school kids when he splatted. The schoolboy he hit was paralysed for life.
That's what I find hard to watch - these men have the right to kill themselves....but what if they hit someone else??
