What stuns me the most, and I mean no offense to our fellow marshals over-the-water, was the fact that Michael was allowed to walk away from his shunt at all. I know that most Corner Workers in the USA are normally there for Flagging/Communication purposes only but surely Simple Green could have detailed someone to escort Michael to a place of safety and watch over him. This is a fundamental rule here in the UK which is drummed into us time and time again at training days. NEVER leave a driver alone after a big shunt.
Michael may have seen to be ok at the time but I know I'm not alone in experiencing drivers collapsing after the initial shock and adrenaline has worn off.
This is in no way a "knock" at my American cousins and please don't take it as such. It is more a general comment aimed at all of us marshals. The driver may well think him/herself to be ok and can be very convincing at the time to those of us with no medical training. The thing to remember is that ANY human-being going through an incident like Michaels is not going to "all-there" for sometime afterwards and needs someone to be near them, and looking-out for them, just in case.
but as MikeK1 said, I too am stunned that anyone was able to walk away from any of the 3 incidents.
