I will give you the same answer as I already have.
OMG...words fail me.
If a police officer tells you to backup. You do it asap.
She did not...and she resisted arrest. So right there that's 2 laws she broke.
And I've found a way to put you on ignore ...happy days
In case you missed it.,
She DID back up, she wasn't given a chance to move further back and she was using a zoom on the camera...(you can hear the instruction, then she's down within about 2-3 seconds).
So by your theory if an officer tells you to backup they can shoot you if you don't move faster than Usain Bolt on steroids?
This is a favourite excuse for police brutality in the US "I issued an order and it wasn't complied with" when the time between issuing an order and taking action is seconds, or the orders were unclear and contradictory, or there was no way to comply (such as the police rounding people up in tunnels or between buildings and two lines of police and ordering them to "dispers" when there is no where for them to disperse to), or the order was given AFTER they took action (as several offficial investigations have found out in regards to use of force on peaceful protestors).
There are numerous videos of officers using the "backup" order then going after the person within seconds, sometimes running ahead of them to be able to say they were not putting distance between themselves and the officers.
I have this odd thing when it comes to the police, I expect them to act professionally, within the law, to be honest, and to be held to account when they do wrong - I expect someone whose entire job is to uphold the law to do so in a lawful manner.
UK police have their faults, but after several decades and the likes of the introduction of the IPCC they are now generally professional, and when they do wrong they are usually accountable with the option for any serious wrong doing to be investigated by people who have no day to day working or personal relationship with the officers and thus are not influenced by friendship or knowing that the person they're investigating can make their own lives hell.
The problem I have with a lot of US police, and it's becoming more and more clear is that they're not accountable, they're not law abiding, and they act like playground bullies rather than with any professional attitude.
IIRC LASD currently has an ongoing federal investigation into "gangs" within it's ranks of officers who are routinely breaking the law under the cover of their badges, their previous chief is (from memory) in federal jail for his antics, and one of the heads of the LA city recently retired with a 1.5 million settlement and full time private security after the head of the LASD got upset about losing a role in the Covid response management team and started accusing her of various things and inciting his officers to harass her.
That's a lovely respect for law and order from the highest levels of the the sheriffs department.
