Securitas is known for having their people wearing uniforms that are designed to be confused with local law enforcement and for heavy lobbying for privatisation of the prison industry in the Nordics.
A great fit for Pinkerton.
Just off the top of my head this is one of the most famous (exposed) examples in the UK https://www.bbc.com/news/uk-47457330
Police were created explicitly to help with suppressing the threat that comes from anyone that earns their living by a wage from others.
but note in the UK this was a major scandal, £250m of compensation paid, etc, rather than business as normal
Your link suggests it took six years for the Metropolitan Police to admit wrongdoing. This camera was found last week. Let’s give it time to actually blow up to “scandal” proportions.
It is a PTZ camera, so I am guessing they are trying to grab license plates.
There is definitely a gray area between private detective work and police assisting with a favor.
It is probable it has nothing to do with politics and the individuals (or people in the area) in question are suspects in a standard criminal activity.
It is also possible it is political.
The lack of transparency in government / police operations leads to this kind of speculation. The massive lose of trust in police (rightfully so) over the past few years also has eroded any "benefit of the doubt" people may have given them in the past
Unless an arrest is made or a lawsuit files we will probably never know the real truth.
