Please stop conflating Black Lives Matter with "Asian Grooming Gangs".
I watched the video on line and read some news this morning. I support the use of police horses, they aren't used to "intimidate", their use is crowd control and to offer some protection to officers attempting to control huge groups of people. Their training, along with that of their riders is excellent. For a police horse to be so terrified it bolts, is rare. The officer hit a lamp post and was thrown, she was unconscious and is in hospital. To fall at speed onto a road suggests she could have been seriously injured, reports say that isn't the case.
The protest was peaceful until around 6 - 7pm when the thugs took over.
I agree with posters here who say the use of the phrase 'all lives matter' is just wrong. Some posters just don't understand or accept white privilege. That is a huge part of the problem faced in the US, the UK and as demonstrations show, throughout the world.
I'm not sure that banning this demonstration would have been possible without riots happening in any event.
Cressida Dick, the mayor, the government have a mountain to climb in preventing further civil disorder. I hope the protesters who threw missiles, threw bikes at police horses can be identified and prosecuted.
