"I didn't have a gun on me, but wish I did," said the man, who was ordering food across from the company's headquarters when the shooting began.  

"I knew I had to be smart. You've got to be fast. You've got to think fast."

Police confirmed that the female shooter, who has not been named, was not a YouTube employee and didn't know anyone at the company.  Witnesses say the shooting broke out at an employee party, which is thought to be how the woman may have gained access to the building.

It didn't take long before the YouTube shooting turned political. After journalist Jack Posobiec tweeted an official report from a local Bay Area news outlet listing the shooter as a "white, adult female wearing a dark top and head scarf," blue-checked Twitter users performed quick mental gymnastics to arrive at the conclusion that conservatives are "spreading vile conspiracies that ANTIFA is behind the YouTube HQ shooting."
