SB1635: New Law on Warning People About Arrests

This bill creates a new crime for knowingly warning a specific person about an immediate police arrest with the intent to stop that arrest.

What This Bill Does

  • Creates the offense of unlawful alerting when someone warns another specific person about a real-time or imminent arrest effort by law enforcement, intending to hinder, delay, or prevent it.
  • Classifies this new offense as a class 1 misdemeanor.
  • Defines 'communicates' to include electronic messages, gestures, verbal statements, signals, written notes, and the use of amplified sounds like bells or whistles for intentional signaling.
  • Exempts attorneys providing lawful legal advice to their own clients from the law.
  • Allows the Attorney General or county attorney to prosecute people who break this rule.

Who It Names or Affects

  • People who knowingly warn a specific person about an immediate police arrest attempt with intent to stop it.
  • Law enforcement officers conducting arrests, surveillance, approaches, pursuits, or executing warrants.
  • Attorneys providing legal advice to their clients during these situations.

Terms To Know

Unlawful alerting
Knowingly telling a specific person that police are about to arrest them with the goal of stopping, delaying, or preventing that lawful arrest.
Imminent effort to arrest
Police actions happening right now or just before an attempt to take someone into custody, such as surveillance, approach, pursuit, or executing a warrant.
Intentional signaling
Deliberately using sound, light, movement, or other conduct specifically to warn or alert another person.

Limits and Unknowns

  • The law does not apply if the warning was given without knowing that the specific person warned is subject to an arrest.
  • The law does not apply if there is no intent to hinder, delay, or prevent a lawful arrest of that specific person.
  • The law does not apply to attorneys giving legal advice to their clients.

Amendments

These notes stay tied to the official amendment files and metadata from the legislature.

Plain English: This amendment changes the law by removing specific examples of police actions, like surveillance or approaching a suspect, that count as an effort to arrest someone.

  • Removes text stating that 'surveillance' counts as part of an imminent or ongoing effort to arrest.
  • Removes text stating that an officer's 'approach' counts as part of an imminent or ongoing effort to arrest.
  • Removes text stating that the 'execution of an arrest warrant' is included in the definition of an effort to arrest.
  • The amendment only removes specific examples from the list; it does not change the general rule about warning someone before they are arrested.
  • Because some technical details were removed, it may be less clear exactly when police actions count as an 'effort to arrest' under this new version of the law.

Plain English: This amendment requires Arizona police agencies to create rules forcing officers to show their name or badge number and banning face coverings that hide identity, with specific exceptions for safety.

  • Police departments must write a policy requiring officers to visibly display their name or badge number while working.
  • The new rule prohibits officers from wearing facial coverings that hide their identity during law enforcement duties.
  • Officers who break these rules and commit assault or unlawful imprisonment lose legal protections and face civil fines of at least $10,000.
  • It is now a crime to impersonate an officer by fraudulently showing government employee identification.
  • The official text provided ends abruptly while listing the specific reasons why an officer might be allowed to hide their identity for safety, so some exceptions are incomplete.
  • Because this is a proposed amendment that failed in committee, it has not been passed into law.

Plain English: This amendment narrows the new law to only punish people who warn a specific individual about an arrest that is happening right now, rather than any person or ongoing police work.

  • The crime now requires warning one specific person instead of just 'any' person.
  • The law only applies when police are making an immediate attempt to arrest someone, not during general or long-term investigations.
  • Technical wording changes were made to clarify how warnings can be sent and what counts as a signal.
  • This explanation is based on the amendment text provided; it does not include details about penalties beyond stating it remains a Class 1 misdemeanor or specific court interpretations of terms like 'imminent'.
