NYPD, and most other big city PDs, are like the McDonald's of LE agencies. Shitty leadership = crappy employees who do stupid *expletive deleted*.
The retired NYPD guy I talked to said the administration is stuck in the 1970s with the added fun of political correctness and affirmative action. You're not going to get good results when the bosses don't care about the job. With McDonalds, it results in an idiot who can't understand the difference between a chicken sandwich and a cheeseburger...with LE agencies it results in cases like this. When there is no real control over the employees there is no control over their actions.
Now in just a few years, where do you suppose all those newly naturalized US citizens , indebted to the Zero, and lacking all cultural ties with the US (us) are going to be employed
Affirmitive action, and consider where the NYPD got its start...Irish immigrants.
Everything old is new again...
