That guy has no idea how hard it is to recruit officers already. The Washington State Patrol has a constant deficit of officers because they can't recruit hard enough to replace retirees and poaching-transfers. Due to regulations on what hoops people have to jump through to qualify to be hired, only a tiny fraction of the population is healthy enough and has a clean enough background to make it.
Then you go and tell them that they are evil and that if they don't do what you tell them to that you will ruin them. Great recruitment message.
I'm actually not at all a fan of the police, I think that they've massively overstepped their bounds on a wide array of issues in the past few decades, but this doesn't seem like something that would work out very well.
