Punishing individual police doesn't change anything about policing's role in society tho
Police chiefs should be accountable too. If they allow unlawful behaviour they get fired.
Also, a lot of police departments in Canada don't even use bodycams. Lack of accountability and transparency.
In terms of their role in society, it should be to enforce the law, warn/fine/arrest lawbreakers, and investigate crimes in order to do such.
For those with mental health issues, disabilities, or having domestic issues there's a role for other professions to help who aren't carrying guns.
