And the legal system upon which we are supposed to rely has raised the white flag to them.
True, although you have to be alive to face the legal music.
Then only time, about 2 decades ago, that I had to use force was to prevent three sheets relieving me of £300 I'd just taken out of a cash machine. They threatened to stab me but hadn't produced a knife so before they had time to think I nutted the closest and felt his face go it, went to punch the second but misjudged it and sort of clotheslined him over the bridge of his nose with my forearm, and then ran like Usain Bolt on acid before the third decided to be a hero.
I never reported it. I'm pretty sure I broke something in the face of the first one and although it was righteous I didn't fancy the grief of hassle at work of being investigated or even suspended. Fortunately it wasn't my home town so there was no chance of me being recognised, and it was long before widespread ANPR so I kept schtumn and a quiet eye on the local news website for that area.
The legal system is all well and good, but even better if you never need to get involved with it.
