A killer pulled out his gun in flagrant moves a few times, and then randomly shot a young man. No one saw him very publicly raise the gun up multiple times because they were all engrossed with their smart phones (and the like) to be aware of their surroundings (h/t – Drudge).

SAN FRANCISCO (AP) — 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.

Before that moment, footage showed the man pull out the .45-caliber pistol and once wipe his nose with the hand holding the weapon, authorities told the San Francisco Chronicle (http://bit.ly/1crPYQc ) in a story on Monday.

“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.”
