The vast majority of these programs are complete garbage. Yeah, it helps a few people, but they tend to come with tons of catches. Almost all crimes should be expungable, or it should be illegal to use the information for jobs/housing (may be trickier, which is why states are going with expungement). There's obvious exceptions, but there's no reason for someone to get denied a desk job, service job, trade/manual labor, due to getting caught with coke or DUIs... I don't care if they have five of them. Sometime within 1-10 years this information should not be used.
