Allegedly.

From our anonymous source, who’s at work in a department store in the mall downtown:

an officer in uniform was shopping with her mom and they watched her pocket some costume jewelry and last i heard they stopped her and called the police, aka her coworkers.

And regarding whether our source was sure it was SFPD:

100% positive. badge, gun, the works.

Crummy.
