Some Wondering Why a Maine Police Department is Using An “Encrypted” Messaging App

According to an article on the WMTW website, some people are wondering why the Portland Police Department occasionally uses the messaging app Signal.  Some people are concerned about some of the features of the app.  For example, similar to Snapchat, messages on the app can be set to delete after 24 hours.

The article explains that the Portland Police Department says it does use the encrypted messaging app Signal, but only in certain situations, like active incidents or when sensitive information is being shared.

In a statement, the department explained the app is simply another tool, similar to a phone call, text, or radio transmission, that helps officers communicate quickly and securely in real time.  Officials say Signal’s end-to-end encryption adds an extra layer of protection, especially during fast-moving or high-risk situations.

At the same time, the department made it clear this doesn’t replace its legal responsibilities.  Under Maine’s Freedom of Access Act, any communication that needs to be saved is still preserved through official record-keeping systems, in line with department policy.

Signal has been under the microscope in recent years, as agencies across the country try to balance secure communication with public transparency.  Critics worry encrypted or disappearing messages could make it harder to keep public records, while supporters say the technology is critical for protecting sensitive information.

Portland police say their use of the app is limited and meant to support their work, not replace official channels or documentation.
