I think the crime a person has committed will cloud their judgment and could ultimately change the way they vote, they'd be voting on the short-term changes of lenient prison sentences or softer laws, than looking at the bigger picture. Yes, they've lost the right to freedom, but they shouldn't be given the right to vote because the way they vote could change the way they were sentenced and any laws regarding prison sentencing, even if they are only in there for 4 or so years.
