Paul,
Let's put it this way, I'm looking at the whole case rather dubiously, considering that the guy lived through it, it sounds like a legal challenge to his employers, what do you folk in the US reckon?.
If I was a presiding judge in this this case I would want REAL pictures of the offending wire and also the report from the EMS team that responded and any PoCo Crew man that responded and also the police report that was filed by the officer(s) sent to the scene by the EMS team.
Until then, there is no case!.
