no. you cannot. ever.
even if you have perfect faith in current government, you're one election away from something different.
CCTV is also extremely ineffective in crime prevention in general, and actually catching criminals - one of few studies(back when i did write my thesis on subject related to it) used different areas of UK to measure crime fighting capability and effect of CCTV - by finding similar areas with and without CCTV and comparing crime statistics.
they only worked on parking lots, there was no measurable differences in plazas, alleys, roads, highstreets etc.
and a bit of anecdotal evidence - once cameras at my older workplace caught robbery to a place next door. With criminal looking directly at the camera, before bashing the window with a brick, jumping in, and hopping out with accomplice. They never got caught. This was quite decent camera, with face clearly visible - i know this because we directly cooperated with police.
Both of them then rely on the next step after providing information, following the people who triggered the first layer with CCTV.
If I went into my local CBD right now, and comitted some badass crime. explode a cop car or something we all yearn to do. All the exits are covered. I wont get anywhere walking and covering my face. I can get on a train but the rozzers will know where I get off. Likewise, if I jump in a car, they can track it almost anywhere for the next 100 kilometers.
I dont think the goal is prevention, its the guaranteed catch. Its the body of evidence that starts piling up when you burn cop car 1.
When brisbane introduced the go card system, we had our first arrest based on go card travel data within a month.
Sad really.

I helped an employer comply like this once. Someone had been brutally killed by a driver. The victim only existed for like 3 frames on the recording. But the cop wasnt interested in that anyway. They had managed to sneak drugs out of their car, into their pocket and then hide them in our garden, mid arrest. Embarrasing for the cop you see. The cop already had the driver on vehicular manslaughter, but thanks to the power of CCTV, they could also add a charge for drug crimes.
It's human to help your friend because they're in need; that's how tribes work. But it's just as human to disparage or sabotage someone who isn't a part of your tribe, to not care about them. To lie and cheat and be corrupt.
As for police effectiveness; there are shady groups of people that hang out in dark alleys in some central London areas every single weekend. You need only walk around/down the wrong place to meet them. All it takes is sting operations where a plainclothes officer acts drunk and hits a "get 'em, boys" button to bring in the fuzz when they inevitably get attacked.
There are all sorts of socio-economic-political issues that contribute to all this, though. But the root problem is in the apathy of the general public, none of us care about anything unless it affects us personally.
You can kinda see that in some parts of the UK still, but certainly lack of staff really affects them; particularly when UK seems to have higher incidences of more violent crimes, more drug related crimes, etc. Turkish gangs shooting little girls in the middle of London.
