maybe its the old man in me, but I'd take a legal car over tinted windows any day....
Are you THAT hell bent on having tint? From your post it looks like you had the tint installed. Did you knowingly chose a % that was illegal or is this a discrepancy b/w MA and RI? One I can fault you for, while the other I cannot.
If it was me I'd remove the tint, but I like to be legal and not get hassled..
