California State Senator Mark Leno is introducing a bill that would require all cellular phones sold in the state to include antitheft technology, reports The New York Times. This measure is being introduced as a way to curb smartphone thefts, which are on the rise in major metropolitan areas like San Francisco and New York City. "With robberies of smartphones reaching an all-time high, California cannot continue to stand by when a solution to the problem is readily available," Senator Leno said in a statement. "Today we are officially stepping in and requiring the cellphone industry to take the necessary steps to curb violent smartphone thefts and protect the safety of the very consumers they rely upon to support their businesses."Co-sponsored by San Francisco’s district attorney George Gascón, this
