In Rhode Island, "disturbing the peace" is generally prosecuted under the same disorderly conduct statute, RIGL § 11-45-1. Some charging paperwork lists "disturbing the peace" as the offense, but it is the same misdemeanor with the same penalties, the same maximum of 6 months in jail, and the same defenses. Other jurisdictions treat them separately; Rhode Island essentially does not. Practical upshot: if your police report or summons says "disturbing the peace," you are looking at a disorderly conduct case. The defenses - lack of intent, First Amendment, reasonable person standard, evidence gaps - are identical. The disposition options - dismissal, filing, diversion, probation, plea - are also identical. Don't get thrown off by the label on the paperwork. What matters is the statute cited, the facts alleged, and the division where you are being prosecuted. Bank & Munns treats every "disturbing the peace" arrest as a disorderly conduct case and defends it the same way.
