Decomp,
Reports say it was a tear gas canister.
He has been upgraded.
Scott Olsen, the Iraq war veteran who suffered serious head injuries after being hit by a projectile fired by police during the Occupy Oakland protests, has woken up and is lucid as he awaits surgery, hospital officials and family members have said.
Olsen, a 24-year-old former US Marine, was struck in the head during anti-Wall Street protests on Tuesday night. He has been upgraded from critical to fair condition.
Olsen "responded with a very large smile" to a visit from his parents, Highland General hospital spokesman Warren Lyons said. "He's able to understand what's going on. He's able to write and hear but has a little difficulty with his speech," Lyons said.
Doctors had not operated on Olsen yet and were waiting to see if swelling in his brain eased, Lyons said.
