Friend just got told to wait a year in Arlington for the restrictions to be lifted after his name appeared on a police report. He is going to appeal it, as the police report was from a few years back, and he was just mentioned as being there with a group when one member did something stupid. He did have to wait 3 full months for the license to come through at all though. They did say it wouldn't have been restricted if he hadn't been in that report.
In Amherst my buddies girlfriend had a quick turn around (35ish days I think) and no restrictions, I should be getting mine up here in a couple months and I expect it will be no different.
Newton MA is still red, when I lived there I was told they don't give unrestricted licenses.
