Starting level and typical ranges
These ranges use the starting level alone, before any adjustments, for someone with no criminal record unless the column says otherwise. Most real cases add levels.
| Starting point | Level | Trial | Guilty plea | Plea + zero-point | Category IV, plea |
|---|---|---|---|---|---|
| How serious was the riot: It created a substantial risk of death or serious bodily injury to someone | 22 | 41–51 months | 30–37 months | 24–30 months | 46–57 months |
| How serious was the riot: It caused a major disruption to the operation of the institution | 16 | 21–27 months | 12–18 months | 8–14 months | 24–30 months |
| How serious was the riot: Neither | 10 | 6–12 months | 0–6 months | 0–6 months | 10–16 months |

Frequently asked questions
What is the base offense level for prison riot?
The guideline for prison riot is §2P1.3 of the federal Sentencing Guidelines. Before any adjustments, its starting level depends on the facts: from level 10 to level 22. The table on this page lists each starting point.
What is the guideline range for prison riot with no criminal history points and a guilty plea?
Using the first starting point in the table on this page (level 22) alone, a person with no criminal history points who pleads guilty scores 24–30 months (2 years to 2 years, 6 months), including the 2-level zero-point reduction. Adjustments such as role in the offense or obstruction can change the level, and the judge can sentence outside the range.
Is probation possible for prison riot?
Not under the guidelines. Even at the first starting point in the table with a guilty plea and the zero-point reduction the range is in Zone D, where the minimum must be served in prison, though a judge may vary below it.
Is the calculator accurate for prison riot?
It follows §2P1.3 of the Guidelines Manual effective November 1, 2025. It passed 5 review rounds, each comparing every number, rule and label with the manual text, and its last round found nothing to correct. Those reviews were done with AI tools, not by lawyers, and it has not yet been reviewed by an attorney, so mistakes are possible. The guidelines are advisory, and a lawyer who knows the case can tell you what actually applies.
