The Met changed their own story, originally it was rape alarms were going to be "thrown at horses" they deleted that and then reworded it to "used to startle horses", they were also ratio'd and fact checked proven to be liars
There's no inconsistency between those statements so I don't know what point you think you are making...
The act of throwing such items at houses could be to startle them.
That doesn't say that the Met lied.
Reading comprehension an issue for yourself?
Yes of course military horses can be and are trained to be more resilient to sudden noises and sudden movements but this isn't a panacea.
Police horses are also similarly trained but can be spooked
by coloured road markings and fireworks
A police horse found wandering streets in east London after becoming startled by a firework is back carrying out duties for the mounted branch.
It had apparently thrown off a police rider when a firework went off nearby.

And I don't think it's been suggested that some of the people arrested weren't acting under a supposed night safety team.
In fact that role is suggested to be key to the action undertaken! By placing the police in an invidious position. A 'volunteer' for said night team, who also coincidentally happens to have previous experience as a 'direct action' protestors for the likes of XR can use their apparent role as a excellent cover.
The police either knowlingly fail to act (and run the risk of a major public incident) or arrest them and wait for the pre scripted faux outrage about them being arrested from people lacking the critical thinking skills to see what's going on!
And again its not as if the police just suddenly made this all up the day before the coronation... heres an article mentioning the issue from the 23rd of April...
Deputy prime minister Oliver Dowden has responded to reports in a Sunday newspaper that activists would cause disruption to the ceremony.

Yet none of them have been charged for any offence despite being caught supposedly red handed by the police for crimes that are punishable with prison or at least a fine
I refer you to my previous posts which have already explained to you that an arrest in and of itself can achieve a legal aim and doesn't have to be undertaken with a view to always leading to prosecution, which after all requires a far higher level of belief than an arrest does....
So again your arguments consistently come from a point of not actually appearing to know what the laws says and what powers police have.
