As we've been reporting, an acquaintance of tech executive Bob Lee has been arrested in connection with his fatal stabbing. Police are not saying how the two knew each other or what may have led to the stabbing. But, the arrest does counter the early narrative that Lee's stabbing was the result of a random crime. Some were using this case to suggest San Francisco is unsafe.   What are they saying now? To answer that question, KCBS Radio's Bret Burkhart and Patti Reising spoke with KCBS Insider Phil Maiter.
