As many others besides Mine Host will know, conversation with a police officer (even of high rank) often leads one to the conclusion that an entry requirement to the police is to fail an intelligence test.
For blokes who are supposed to be "trained investigators" quite a number exhibit awareness skills akin to those of a wooden plank.
Mine Host would be wealthy indeed had he a gold bar for each time a police officer of the rank of Sergeant, Senior Sergeant, or Inspector has said to him: "You pubs fill people with grog, then when the punter's pocket is empty of coins you throw them out onto the street, and create a police problem."
It takes a special arrogance, a belief in the superiority and in the infallibility of one's own opinions, and no sense of shame or embarrassment (not to mention crass stupidity) to make such a statement in public.
Mine Host long ago gave away the notion that promotion to Sergeant & above meant an officer had some street smarts & savvy. Actual contact of an official nature with officers ranked Sgt & above put paid to that. Some of them are as dumb as a box of rocks.
In a Constable this is manageable, in a Sgt or Inspector who turns out backward enough to believe the above statement should be a serious policing policy, it can become a tedious problem.
For as anyone who has any dealings with the liquor industry (except it would seem, a whole lot of senior cops) is well aware, as far back as 10 years ago RSA laws (Responsible Service of Alcohol) closed the door on the flimsy claim that such circumstance was the norm.
