Better tell a certain London mayor that and members of the Labour Party.
Stop and search works.
End of.
Also. Carry a knife, get caught. Custodial sentence awaits.
Stop and search does not work - even when it's not implemented by people witt prejudices.
The incident in question wouldn't he beon avoided by stop and search - unless you think there should be police on every street corner, stopping and searching everyone.
I suspect that you believe that it's other people who should be stopped, not yourself?
