Regional Overview

6 States Analyzed
87 Encrypted Agencies
38 Remaining Open
1 State With Media Access Law

The Mountain West region spans from the Rocky Mountains to the Mojave Desert, covering diverse communities from ski resorts to border towns. This analysis examines encryption trends across Colorado, Arizona, Nevada, Utah, New Mexico, and Idaho.

The region demonstrates both the worst and best of encryption policy. Arizona and Nevada have nearly complete encryption in major metros. Meanwhile, Idaho's Boise remains open, and Colorado passed the nation's first statewide media access law.

Unique regional factors complicate encryption: wildfire evacuation coordination, tourism infrastructure requiring multi-agency response, and 1,954 miles of international border with Mexico necessitating interoperability.

Patterns Unique to Mountain West

Tourism Corridors

Las Vegas, Phoenix, and Colorado ski towns draw millions of visitors annually. When emergencies strike tourist areas, encryption blocks the rapid information dissemination these transient populations need. The 2017 Las Vegas shooting demonstrated how visitors lack local alert systems.

Affected Areas:
  • Las Vegas Strip and Convention Center
  • Phoenix/Scottsdale resort corridor
  • Colorado I-70 ski towns (Vail, Aspen, Breckenridge)
  • Utah ski resorts (Park City, Snowbird)
  • Grand Canyon and Sedona tourist zones

Border Region Complexity

Arizona and New Mexico share 1,954 miles of border with Mexico. Border Patrol, state police, local agencies, and tribal police must coordinate constantly. Encryption creates walls between agencies that need seamless communication.

Coordination Challenges:
  • Tucson sector: 262 miles of border requiring multi-agency response
  • Phoenix-area immigration enforcement coordination
  • New Mexico tribal lands spanning border regions
  • Cross-border emergency medical services

Wildfire Response

The Mountain West faces increasing wildfire danger. Colorado's Marshall Fire (December 2021) destroyed 1,000+ homes near Denver. Encryption blocked real-time evacuation information while encrypted agencies coordinated behind closed communications.

Recent Wildfire Challenges:
  • Marshall Fire (CO, 2021): 6,000 acres, 1,000+ structures, encrypted response
  • Cameron Peak Fire (CO, 2020): 208,000 acres, largest in state history
  • Arizona Tunnel Fire (2022): Flagstaff evacuations with encrypted coordination
  • Nevada Tamarack Fire (2021): Multi-state response challenges

Rural-Urban Divide

Mountain West states have vast rural areas where encryption is impractical. Rural sheriffs often maintain open communications for volunteer coordination and long-distance mutual aid. This creates islands of transparency surrounded by encrypted urban cores.

Open Rural Areas:
  • Eastern Colorado plains counties
  • Northern Arizona Navajo Nation (tribal sovereignty)
  • Nevada rural counties outside Las Vegas/Reno
  • Southern Utah wilderness regions
  • Most of Idaho outside Ada County

Colorado HB21-1250: A Regional Model

Legislative Victory

First Statewide Media Access Requirement

In 2021, Colorado became the first state to pass legislation requiring police departments with encrypted systems to create media access policies. HB21-1250 mandates that agencies establish procedures for credentialed journalists to access encrypted communications.

What It Requires:

Agencies must create written policies for media access to encrypted radio systems, including credentialing procedures and access protocols.

Who Championed It:

Rep. Kevin Van Winkle (R-Highlands Ranch) attached the amendment to broader police accountability legislation after three years of standalone bill failures.

Implementation Status:

Denver and Aurora have yet to reach workable agreements with news organizations. The law lacks enforcement mechanisms for non-compliance.

Lessons for Other Mountain West States

  • Attach to broader reform: Standalone encryption bills failed three times; attaching to accountability legislation succeeded
  • Build bipartisan coalitions: Republican sponsor gained Democratic support by framing as government accountability
  • Include enforcement: Colorado's law lacks teeth; future legislation should include penalties for non-compliance
  • Engage broadcasters: Colorado Broadcasters Association provided sustained lobbying support

Boise: Regional Model for Transparency

Success Story

Why Idaho's Capital Remains Open

While Phoenix, Las Vegas, and Denver have gone dark, Boise and the Treasure Valley maintain open police communications. The Boise Police Department, Ada County Sheriff, and surrounding agencies continue to allow public scanner access.

What Makes Boise Different

Strong Open Government Culture

Idaho's political culture emphasizes government transparency and citizen oversight.

Community Engagement

Active scanner community and local media have maintained pressure for transparency.

No Major Catalyst Event

Unlike Las Vegas (1 October) or Denver (2020 protests), Boise hasn't had a triggering event used to justify encryption.

Practical Interoperability

Rural Idaho agencies rely on open communications for mutual aid; encryption would isolate Boise from regional partners.

Partial Access Model

Ada County Sheriff maintains a hybrid approach: main dispatch and routine operations remain open, while specialized tactical channels (SWAT, undercover operations) are encrypted. This balances legitimate security needs with public transparency.

Take Action in the Mountain West

Support Colorado Implementation

HB21-1250 passed but implementation has stalled. Contact the Colorado Broadcasters Association and your state legislators to push for enforcement mechanisms. The law only works if agencies comply.

Colorado Broadcasters Association

Push for Legislation in Arizona

Arizona has no transparency protections. With Phoenix and Tucson fully encrypted, advocacy efforts should focus on the state legislature. Use Colorado's HB21-1250 as a template for Arizona legislation.

Prepare testimony for Arizona Legislature

Preserve Idaho's Transparency

Boise's open communications aren't guaranteed. Attend city council meetings when radio system upgrades are discussed. Public awareness prevents quiet transitions to encryption.

How to fight encryption proposals

Document Wildfire Coverage Gaps

When wildfires strike encrypted areas, document how encryption affected information flow. These real-world examples build the case for transparency requirements.
