Police academy is way too short, it takes a lot longer to become a barber/beautician in the states.
Mandatory body cams. Disciplinary action if cops turn off their cams.
Abolish no knock warrants.
If a police officer is just starting out and is not from a particular community then he/she should work basketball, football, other sporting events, etc. This is to get acquainted with people in the community. Bring community policing back.
If a cop is involved in a shooting or use of force incident, blood work must be done for alcohol/drug use.
Officers that have been involved in shootings, use of force, etc should have a quarterly psych evaluation.
Officers that are fired for misconduct as it pertains to citizens should be deemed unhireable. That way they cannot go to the next town over and start again.
Solid suggestions.
