Would you wear a uniform that evokes fear & distrust in your neighbors?
Would you risk your mental well-being, affecting you & your loved ones?
Would you be comfortable with helping send someone to prison for years because of a petty parole violation or non-violent offence?
Would you participate in actions that split apart families?
Are there other ways you can build safety, beyond policing, in your community?
Except that all 3 of the alternatives have absurd qualification requirements and will pay far less and have far fewer material benefits than becoming a cop.
