Life in Washington seems to revolve around smartphones. Almost everyone uses them, some people steal them and officials search for ways to protect them. But something that happened this week suggests one possible solution to the plague of phone thefts:

Keep Cmdr. Jacob Kishter, who heads the 3rd Police District, on the street night and day. Thursday evening, for at least the second time in a year, the sharp-eyed, fleet-footed Kishter chased down a suspect in a phone theft.

By coincidence, Sen. Barbara A. Mikulski, (D-Md.) held a news conference Thursday to report legislative efforts to curb the “growing crime’’ of phone theft. “I’m going to do something about it,” Mikulski said.

About 6 p.m. that day, a phone was snatched from a woman near Fifth and C streets NW, D.C. police said, and Kishter and the police official who was with him did do something about it.

After shouts drew the attention of Kishter and Cmdr. Keith Williams, a foot chase began and went on for a few blocks. Then, Kishter said later, “the kid just gassed out.” He “kind of said, ‘You got me.’ ”

Last March, Kishter caught another phone-theft suspect after a five-block foot chase.
