You missed my point which was in response to Freda's question on how does she kill her crayfish. It appears that a cray in a restaurant has more important feelings because it is commercial. The law only applies to the commercial killing of crays. Presumably amongst the 3,000 MPI employees each earning $115,000 a year we now have commercial cray killing inspectors. No doubt they regularly check the electric stun guns they recommend to use.
The reference to the commercial fishing boat was asking how is a crayfish anymore of a sentinel being than a schnapper?
