Mountain West Police Encryption Trends
From Las Vegas casinos to Colorado ski towns, the Mountain West presents unique encryption challenges. Tourism-dependent economies, wildfire-prone landscapes, and expansive border regions create communication needs that encryption complicates.
Regional Overview
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.
- 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.
- 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.
- 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.
- 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
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.
Agencies must create written policies for media access to encrypted radio systems, including credentialing procedures and access protocols.
Rep. Kevin Van Winkle (R-Highlands Ranch) attached the amendment to broader police accountability legislation after three years of standalone bill failures.
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
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
Idaho's political culture emphasizes government transparency and citizen oversight.
Active scanner community and local media have maintained pressure for transparency.
Unlike Las Vegas (1 October) or Denver (2020 protests), Boise hasn't had a triggering event used to justify encryption.
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 AssociationPush 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 LegislaturePreserve 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 proposalsDocument Wildfire Coverage Gaps
When wildfires strike encrypted areas, document how encryption affected information flow. These real-world examples build the case for transparency requirements.
