I think something that hasn't been discussed much, is how the world of fake news, nonsense and conspiracy theories also damages the police.
In the last 10 years, there's been a number of high-profile incidents, (Mark Duggan, Yasser Yaqub, to name 2) where the police have performed a planned operation, somebody has ended up being shot dead for reasons which largely make sense. However the fallout of this tends to spawn a wave of conspiracy theorists and also media moguls, who attempt to 'investigate' the incident. In doing do, they draw their own conclusions, often from incorrect or distorted information, where the actual outcome has been pre-determined ahead of any actual analysis of the evidence.
The end result is the decisions which are made by the police, get repeatedly thrown under the limelight, often where the intention is simply to write a book, or shoot a documentary and make money, where facts or evidence are often substituted for pure fantasy and hyperbole. (Making a murderer would be a perfect example of this) Often casting a known, harmful, obviously-guilty, dangerous criminal - with a history of convictions and violence, as an Angel who could never hurt anybody.
I think the 2019 world of information distortion, spin and essentially outright lies - circles back, and actually erodes trust in the police and the authority of law as a whole. Not because the law or the police are fundamentally bad, or make mistakes, but simply; you can make a lot of money, and generate a lot of 'clicks' from seeding that narrative in the public mind, and I think it's now starting to hurt us as a society.
I'm not suggesting for a moment, that if the police ever get something wrong they should be left alone with impunity, because they should ultimately be accountable for the decisions they make. The problem is, every time an incident occurs, the default response is to cast a huge shadow of distrust on the police and come to the hasty conclusion, that they must have 'gotten it all wrong' or they 'had it in for that guy from the start'. When actually, when you look at the evidence, the guy had it in for himself from the start because he was a highly dangerous criminal who needed to be behind bars.
