Real world example.
Sample size of one.
It may depend where you are. I'm in NZ.
In August 2022 I disarmed a knife wielding attacker who was attacking pedestrians. Possession of a knife of the size involved in public is an offence.
The police said that when they watched the video (local Town Hall entrance ) they were impressed.
The regional police commander made favourable comment to the local news media.
I conclude that the police consider my possession of the knife legitimate :-)
