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?
So does the police hiring process.
Okay, you have a filter which takes normal people and assholes and remove most of the normal people. Why would you want to reduce percentage of normal people and add more assholes to the input mix? That will make things even worse.
Because the goal is not to have normal people as cops, it’s to have people willing to enact state violence for arbitrary reasons.
