It would depend on how long ago it was, their age at the time etc.
This poses an interesting question. Would you vote for a councillor with a conviction for: -
speeding
common assault
domestic violence
GBH
drink driving
driving an untaxed vehicle
theft
drugs (class a)
cannabis
...or maybe an ASBO?
Personally I dont think you can make a generic judgement - the circumstances should be fully investigated and an informed decision should be made by a representative panel of people.
I don't think we at Accyweb will ever be privy to that level of information
