Re: This seems similar to the global snooping (encryption) issue.
"Yes, of course you have to take into account the incompetence/corruption while evaluating the evidence"
"Taking into account" the level of corruption in the Police?
Are you even serious? No-one can estimate how much Police is lying in just this case at any accuracy, therefore totally absurd mindset.
Totally fascist it becomes the moment you realize that the 'innocent until proven guilty' is basically thrown into trash bin and whole court exists to judge how much Police is lying and presenting totally made-up evidence in this case.
As the court can't do that, everything Police brings into court, will be taken at face value, i.e. truth.
No matter how obviously fake it is: The Judge isn't there to estimate the honestness of the Police, but honestness of the accused.
