Where have you heard of the 4 window cleaning deaths this year ?
Various posts on other forums.
The guy who used WFP and fell from ladders on the fussy customers house was a good friend of Scrimmans. There's a sticky thread on ACS entitled "Reasons to go WFP" with a couple of the other stories too.
I personally know 2 guys who have been seriously injured falling from ladders. 1 broke his back,.. the other shattered his leg in 13 places and destroyed his ankle,... he's lucky he's able to walk again, although he is in constant pain and has a serious limp now.
