Haven’t you claimed that cops in general can’t be trusted and are liars? Yes or no?
Cops lie as part of their job. That’s how they get information and elicit confessions. They teach it in criminology. How many of them in uniform lie for personal gain and to get themselves out of trouble? Well let’s see...take 100 police officers, subtract the number that are saints, and you’ve got your percentage.
Are all people in any given profession either liars or truth tellers? Yes or no.
