evidence: City officials did not post street signs in San Francisco that appeared to warn thieves that "stolen goods must remain under $950," the city’s Board of Supervisors president said. The city has removed the signs. Proposition 47, a California ballot measure voters passed in 2014, lowered some nonviolent felony crimes to misdemeanors, including shoplifting, as long as items taken totaled less than $950. People convicted of that crime face six months in prison and/or fines of up to $1,000.
