Allow the people to record traffic stops, home encounters, etc too.
Also, require the officer to help re-pack your vehicle and/or pay for any damages to vehicle after a non-consentual search.
Hold the officer/dispatcher/who ever is at fault- individually responsible financially (instead of the dept./taxpayer) for damages resulting from 'breaking down the wrong door'.
Confiscating large amounts of cash because they 'suspect you might use it for drugs' needs to be illegal unless there's actual proof of drug use/traffic.
Do away with speeding ticket, etc, quotas.
Ensure officers are well versed and understand concealed carry and other gun laws/definitions.
Probably some others I can't think of at the moment.
