San Francisco Train Passengers Too Distracted By Phones To Notice Shooter's Gun In Plain Sight

While smartphones have been used as a civilian tool for reporting crime, recent footage from a San Francisco murder scene has safety officials more concerned that handheld technology is making people oblivious to their surroundings.

The San Francisco Police Department says that security footage reveals the alleged killer of a young man on a San Francisco light-rail train had his weapon out in plain sight, the San Francisco Chronicle reported. But what investigators found more alarming is that none of the other passengers noticed because they were staring at their phones.
