The police woman's physical injuries are serious enough to keep her away from work for a long period. I just hope we as a society don't lose another brave officer because her physical or psychological fitness doesn't recover to the extent she is fit enough for the demanding job she does.
In the past, Ive joined marches where police horses were used, and those where they weren't. I've worked with Officers from the dog and mounted units and seen the horses in training. As merlotgran said, only the most experienced horses would be used in a demonstration like the one seen in London.
The reason I don't believe its appropriate to conflate the Asian grooming gangs with the BLM demonstrations, is because they just don't compare. BLM is a response to institutional racism and this weeks protests a direct response to the murder of a black man by a white police officer. The fact it happened in the US doesn't make it only their problem. It's a universal problem.
To say that "we just took it" in relation to the Asian grooming gangs is incorrect. Many social workers, health workers, teachers, police officers etc were raising their concerns about the sexual exploitation of girls (and boys) from the mid 1990's. My experience was it wasn't fear of being accused of racism that stopped cases progressing, more the institutional dismissive response to children who were wrongly dismissed as "making life style choices". Yes, indefensible and eventually things began to change. Without protests from (mainly) women in public service that wouldn't have happened.
Sadly, I don't see how a rise in the R rate can be prevented and these demonstrations must add to the risk. Horrible events.
