Stop criminal records for small offences
I'm particularly thinking of Local Govt here. You can get criminal records for dropping litter, leaving your bin out on the wrong day etc etc.
Criminal records for serious crimes only. Will free up the courts and save money.
Why does this idea matter?
People are being criminalised for petty things. This is an expensive process that takes a long time. Plus it will severely hinder those who get a criminal record from getting/changing a job.
