Was the police action justified by the reason they gave for stopping the car, which was that it was being "driven suspiciously." What exactly does that mean? When I'm driving, I'm suspicious of every other road user in case they do something stupid and cause an accident. That was just a catchall excuse, made up after the event and impossible to disprove, to hide the real motive, which is a product of police officers' limited intelligence.
To illustrate, here is a syllogism:
All criminals drive expensive cars
X is a criminal
Therefore X drives an expensive car
The third statement is a logical deduction from the first two. A false syllogism is this:
All criminals drive expensive cars
X drives an expensive car
Therefore X is a criminal
The third statement is not a logical deduction from the first two, except in the small minds of police officers when they see a black person driving an expensive car. When the stop and search policy is racially applied in that way, it is no wonder that black people are upset. I heard only yesterday that 80% of recent searches of black people resulted in no further action. That does not show police intelligence.
As for Cressida Dick, what an appropriate name for the head of the Met.
