TL;DR: Max of 5 years, most are 3 months to a year and/or a fine (depending on severity). Organizers get 5 to 8 years.

I don't know how many people they plan on actually convicting, but I think they're absolutely going to go after the ones that started it. Seems pretty fair and I've read that Cuba's prison system isn't caging so much as being forced to go to socialist camp and do farm labor for minimum wage. I don't know how fully they remove people from their communities, but I think the ones that accept the plan progressivo stuff get weekend release, conjugal visits, and basically just have to wear a shirt that says "I'm a reactionary".
