Perhaps this is a good time to point out a few things.
This was in the USA, in a state not known for good cops, and the group was training for a country sherrif department. The entry standards for police in the USA are certainly lower than in Canada, and the applicants , in my opinion, are less well educated and more likely to be border line in terms of fidelity to the concept of being "the best ".
It is not an accident that the stereotype of the "big ole Georgia Sherriff " is seen time after time in movies. In oder to have a stereoytype, there has to be a real life model . Sounds like 22 of them just got shown the door.
