A report which offers a two-dimensional view of the problem, of more correctly, the parts you quote offer one aspect.
Lets look at it another way, the majority of Scots portrayed in british tv are stereotyped as drunken and homeless. If the majority of scots in london actually were drunk and homeless, and you approached one who was not drunk and had a home to go to, you would most probably respond to them as if they were pished and had nowhere to go and then you would be initially shocked that the stereotype had not been supported.
So, if a police officer approaches a suspect, who is stereotyped as likely to be aggresive, then the police officer would be justified in being cautious and ready to respond with force. Is that the police officers fault, or is it because that stereotype is built up from actual incidents where the stereotyped suspect (either by race, gender or some other characteristics) has been proven to be aggresive.
That statement about "officers appear to assess threat differently depending on the race of the subject" could well be racism, or it could also be that the subjects of a specific race are more likely to be aggresive when confronted by police. Chicken / egg, but you can't just point at the figures without understanding the reasons.
On another subject, apparently "erasing the past" is not just a thing for 1984 and is acceptable for the media to say.
