I think that historically law enforcement and intelligence agencies are strongly leaning to the right. They use the power granted by citizens to do their jobs and use it to pursue their personal political agendas.

"The activist, Kate Wilson, had a two-year intimate relationship with Mark Kennedy, who was known to her as Mark Stone. She only found out in 2010 that he had been an undercover officer tasked with infiltrating environmental protest groups." https://edition.cnn.com/2018/09/21/uk/uk-police-spy-activist...

Instead of investigating power corruption, the relationship between far-right groups and Russia, etc. UK thinks that infiltrating "environmental groups" and using government resources to allow an spy to have sex with an activist is more important, because "environmental activists" are bad...

Law enforcement and intelligence agencies around the world have a problem with lack of professionalism were personal political agendas triumph doing the duty that they have been tasked to do. That is why they are so inefficient and things like the Russian meddling with Brexit and the USA elections happen.
