The man drew the gun several times on the crowded San Francisco commuter train, with surveillance video showing him pointing it across the aisle without anyone noticing and then putting it back against his side, according to authorities.
The other passengers were so absorbed in their phones and tablets they didn't notice the gunman until he randomly shot and killed a university student, authorities said.
"These weren't concealed movements — the gun is very clear," District Attorney George Gascon said. "These people are in very close proximity with him, and nobody sees this. They're just so engrossed, texting and reading and whatnot. They're completely oblivious of their surroundings."'
The next time you are out in public, put in your ear buds, and zone out while connected online, just remember even though your mind has "left the building", you are still actually physically present..
Sometimes ignoring your surroundings is the wrong thing to do. In this case, everyone was so spaced out they were all sitting ducks.
So ask yourself: when was the last time I was so plugged in that I missed something big? Has anyone had a life threatening experience due to being on line at the wrong time?
