3.4 Offenses Against Public Administration, Peace & Order

Key Takeaways

  • Resisting Arrest (C.R.S. § 18-8-103, Class 2 Misdemeanor) requires physical force or creating a substantial risk of bodily injury against an officer acting under color of official authority; under Colorado law, the illegality of the arrest is NOT a legal defense.
  • Obstructing a Peace Officer (C.R.S. § 18-8-104, Class 2 Misdemeanor) requires a physical act or verbal threat of physical act that hinders or impairs official duties, whereas passive non-compliance or mere verbal argument is insufficient.
  • Disarming a Peace Officer (C.R.S. § 18-8-116) is a Class 4 or Class 3 Felony that criminalizes knowingly removing or attempting to remove a firearm, Taser, baton, or chemical agent from an officer's person.
  • False Reporting to Authorities (C.R.S. § 18-8-111) criminalizes false 911 calls, fake crime reports, and 'swatting', which elevates to a Class 3 or Class 4 Felony if tactical emergency responses or serious bodily injuries result.
  • First-Degree Perjury (C.R.S. § 18-8-502, Class 4 Felony) requires a materially false statement made under oath in an official proceeding, whereas Tampering with Physical Evidence (C.R.S. § 18-8-610, Class 6 Felony) prohibits destroying or concealing evidence to impair its availability.

Resisting Arrest — C.R.S. § 18-8-103 (Class 2 Misdemeanor)

A person commits resisting arrest if they knowingly prevent or attempt to prevent a peace officer, acting under color of official authority, from effecting an arrest of the actor or another by:

  1. Using or threatening to use physical force or violence against the peace officer or another; OR
  2. Using any other means creating a substantial risk of causing bodily injury to the peace officer or another (e.g., flailing arms violently, thrashing, or wrestling with an officer).

[!IMPORTANT] The Colorado Unlawful Arrest Doctrine (C.R.S. § 18-8-103(2)): It is no defense to a charge of resisting arrest that the peace officer was attempting to make an arrest that was in fact unlawful, provided the officer was acting under color of official authority and was not using unreasonable or excessive force. Under Colorado law, citizens must submit peacefully to arrest and seek remedies in the courtroom, not through physical resistance on the street (People v. Hess, 1984).

Obstructing a Peace Officer — C.R.S. § 18-8-104 (Class 2 Misdemeanor)

  • Elements: A person commits obstructing a peace officer, firefighter, or emergency medical service provider if, by using or threatening to use physical force, or by knowingly creating an obstacle or hindrance by any other physical act, or by verbal threat of physical action, they knowingly hinder, impair, or obstruct the performance of official duties.
  • The Physical Act Requirement (Dempsey v. People, 2005): Colorado courts have firmly established that mere verbal criticism, shouting, refusal to answer investigative questions, or refusal to exit a vehicle upon a consensual contact does not constitute obstruction. There must be an affirmative physical act (e.g., standing across a doorway to block access, running away from a lawful Terry stop, or physically pulling a companion away from an arresting officer).

Disarming a Peace Officer — C.R.S. § 18-8-116

  • Elements: Knowingly removing or attempting to remove any weapon from the person or immediate control of a peace officer performing official duties without consent.
  • Classification:
    • Class 4 Felony: Removing or attempting to remove a conducted electrical weapon (Taser), baton, or chemical agent.
    • Class 3 Felony: Removing or attempting to remove a firearm.

Refusal to Aid a Peace Officer — C.R.S. § 18-8-107 (Petty Offense)

  • A person commits a petty offense if, upon a command by a peace officer acting under color of authority, they unreasonably refuse or fail to aid the officer in effecting an arrest or preventing an offense, unless physically unable or compliance poses grave personal peril.

2. Obstruction of Justice, Perjury & Tampering (C.R.S. Title 18, Article 8, Parts 1, 5, 6)

False Reporting to Authorities — C.R.S. § 18-8-111

  • Misdemeanor Violations (Class 2 Misdemeanor / Petty Offense):
    • Knowingly causing a false alarm of fire or emergency to be sounded;
    • Making a false report of a crime to law enforcement or emergency dispatch;
    • Providing a false name, birthdate, or identification to an officer during lawful detention or arrest.
  • Felony "Swatting" Mandates (C.R.S. § 18-8-111(2)):
    • Transmitting a false emergency report knowing it is likely to cause an emergency tactical response (SWAT deployment) is a Class 4 Felony.
    • Elevates to a Class 3 Felony if the swatting response proximately causes Serious Bodily Injury or Death to any person.

False Swearing§ 18-8-504Makes a false statement under oath where materiality is not required.Petty Offense

Tampering with Physical Evidence — C.R.S. § 18-8-610 (Class 6 Felony)

  • Elements: Believing that an official proceeding is pending or about to be instituted, a person destroys, mutilates, conceals, alters, or removes any physical evidence with the intent to impair its verity or availability.
  • Common Patrol Scenario: A suspect during a traffic stop swallows a plastic baggie of illicit narcotics or throws a handgun into a storm drain upon seeing police overhead lights.

3. Offenses Against Public Peace & Order (C.R.S. Title 18, Article 9)

Disorderly Conduct — C.R.S. § 18-9-106

  1. Make a coarse and obviously offensive utterance, gesture, or display in a public place, tending to incite an immediate breach of the peace (Petty Offense);
  2. Make unreasonable noise in a public place or near a private residence they have no right to occupy (Petty Offense);
  3. Fight with another in a public place (Class 2 Misdemeanor);
  4. Not being a peace officer, display a deadly weapon, display any article used or fashioned in a manner to cause a person to reasonably believe that the article is a deadly weapon, or represent verbally or otherwise that the person is armed with a deadly weapon in a public place in a manner calculated to alarm (Class 2 Misdemeanor);

Bias-Motivated Crime ("Hate Crime") — C.R.S. § 18-9-121

  • Elevates harassment or property damage when committed with the intent to intimidate or harass another person because of that person's actual or perceived race, color, religion, ancestry, national origin, physical or mental disability, or sexual orientation.
  • Inflicting bodily injury during a bias-motivated offense elevates the crime to a Class 4 Felony.
