I think its because the fact that police are getting more harsher criticism these days due to the shooting incidents of unarmed folks. If you do become a police officer in these times good luck with dodging bullets from those who really want cops dead.I've read a lot about how at the moment there aren't a lot of people who are interested in police academies.
Why do you think that happens? Is it because the salary? Or is it because nowadays it's very risky? Is it worth to pursue this career?
