Vulver... It would appear to me that as a TRE checks and a TRI trains, then one could expect a TRE to end up giving more 2s and 1s than a TRI. So would it not be a reasonable question at an interview, to ask the TRI about why he/she has or has not had to fail anyone in training as this would be very likely in his/her new position? To suggest that a question implied that not enough 2s and 1s had been given is a bit steep, unless of course they had been guilty of over-marking.
I think it was that suave British spy, James Bond who was given "license to kill", I doubt a Texan Sheriff would need a license for anything....
