Thats not all that contradictory
The police manage to put up millions of spy cameras and then claim they are not on, are not working properly, are unable to identify perpetrators. Why are the police spending millions of my pounds on crap that doesnt work.... or are they downright lying about them not working? Given the police are massively lazy about actually investigating any crime I suspect they are downright lying about how ineffective these cameras are.
So I conclude they are effective and are spying on us but dont want us to know which makes it even more suspicious. Do I trust our police? Not a chance, you only have to look at the number of times they have been caught lying and killing innocent people.
