To many Arlington residents, the announcement that police chief Fred Ryan is retiring, effective January, came as a bombshell.

Town leaders say he’ll be leaving a very different police force than he found 20 years ago. Under Ryan’s leadership, the Arlington PD has become a national model of the modern, community-focused agency.

In his first APN interview since the announcement, Jeff Barnd talked to Chief Ryan about his tenure, his accomplishments, and the future.
