If as a police person ( let’s be PC here) you are offended by bad language during a training session. ..then you need to reassess your job
Can you imagine a guy with a sawn off saying…”oh good morning Mr Policeman…do stand over there old bean as I don’t want you to get hurt..there’s a good thing”….
Or will he come out with that many expletives your brain would just blow…..
If they can’t stop being offended then maybe they should stop being the police.
