That's sure to be the debate in the coming days in weeks in the wake of a fatal shooting of a Berkeley grandmother by a city police officer over the weekend. According to the Oakland Tribune, several East Bay police agencies use Tasers, including Oakland, Livermore, Pleasanton, Fremont, and Union City — but not Berkeley. Tasers shoot off a strong electronic jolt, and cops use them to subdue unruly and dangerous suspects. If Berkeley police Officer Rashawn Cummings had a Taser, 51-year-old Anita Gay might still be alive.
