I'm afraid I don't believe you , perhaps you could specify where you witnessed these incidents you claimed .
FWIW I have witnessed 12 "offs" and assisted the paramedic when we had one otherwise I was on my own with the rider. Your broad assertion that "marshals haven't got a clue and run around flapping " is offensive and untrue.
Out or the 12 , 2 were "fatals" ,neither of which fitted your description of the aftermath of a "fatal" and both were a result of the initial point of impact trauma .
I no longer marshal as I feel the CoC has a cavalier attitude to rider safety ( see my previous posts ) and I do not accept the instruction that irrespective of the circumstances riders should be dragged off the road and 'rolled' onto a 'scoop stretcher' . I have yet to meet a paramedic who would agree with that instruction and not split the scoop stretcher when a rider clearly may have leg/pelvic/ internal injuries .
A number of local marshals opted not to marshal because they could not , as required by the ACU / CoC obey ( without question), adopt and applaud all the decisions / instructions of the COC . Failure to do so would involve the diciplinary procedure and being told your services were no longer required ( see the sacking of the CSM Sector 10 by the CoC when (comically), he actually had no authority as he held no position in the IOMTT MA , but later apparently ratified (?) )
I think the "cock" you refer to is in fact you blade runner. hope this helps .
Just saying
