Yes, exactly. One of the things we proposed in one of the documents we sent to the government was a multi-tiered system that responded to different kinds of offences.
For example, it makes sense if you have only one conviction for simple cannabis possession that's over 40 years old and you've never done anything since then. Who cares? Just expunge it. It's so useless to have that.
In terms of the risk of it being anything more serious than simple cannabis possessions, if they're 40 years old, why don't we just get rid of all those ones? Different tiers of types of offences can attract different responses.
