Actually, I would say we can't trust law enforcement these days
Law enforcement is consistently trying to hide what they do, consistently saying the law means what they say it means, and consistently ignoring the constitutionality of what they do, and colluding to commit perjury by hiding the truth about how they found certain information.
When law enforcement stops caring about the law
Pretty much all law enforcement these days feels it operates in a special magic bubble.
The rest of us say "fuck that, follow the low, or be charged under it".
General warrants, probable cause, free from unreasonable search and seizure
So, no, we cannot fucking trust law enforcement. Because they are no longer trustworthy.
