I often see images on the TV news of police officers trying to deal with violent and confronting situations. What I see makes me cringe.
I see officers dressed in flak jackets and military style helmets, wielding pistols, batons, capsicum spray, taser darts and even military assault rifles; most of those things I never had and would not have wanted to use when I was a plod. And surely police officers are not soldiers, they are members of the community appointed as officers of the law, they shouldn't need to use soldiers weapons.
I am convinced that the most effective items in the law officers " armoury " should be 1. Head for thinking 2. Eyes for looking 3. Ears for listening and most importantly.... 4. Mouth for talking. Effective dialogue is of much more value than force. Also 5. The little pocket notebook. Recording evidence correctly has brought justice on many occasions.
In other words, if you have your wits about you, things can be resolved constructively. Force tends to be destructive.
I can recount one event, however, where I badly misjudged the application of the vital tools of wit and wisdom ( only one... well

We went to a so-called domestic trouble. A big bully of a bloke had beaten up his lady, so we decided that he had to be taken in to face the magistrate. Being arrested didn't suit him and on this occasion the use of a bit of physical force was necessary to bring this bloke to justice.
As we bundled him into the back of the waggon, his lady was standing nearby. I decided to say something encouraging to her in case she was thinking of changing sides ( which can happen when a person sees their other being manhandled by cops )
So I said to her " I haven't much respect for a man who beats up a woman. Especially a pregnant woman " I glanced at her swollen torso.
She replied rather tersely " I am not pregnant "
" ah...er....um...OH !! "

As a postscript to the assault charge, this fellow pleaded not guilty and in the court case, his lady did change sides and lied in the witness box to support his denial. Unfortunately for them, when the bloke got in the witness box, being the coward that he was, he caved in to the prosecutors cross examination and confessed his guilt.
One good thing, I never again heard of any strife between them.
I learned a valuable, if painful, lesson in ; look, think... then speak.
After that I was very circumspect on delicate women's issues.
