Scott Olsen, the Iraq war veteran who suffered a fractured skull during an Occupy Oakland protest, said police still have not interviewed him about the Oct. 25 incident.

In his first video interview since his release from the hospital, Olsen told Indybay his prognosis is not certain, because the "brain is unique in how it works." (The interview is posted on YouTube.) But he said he is hoping for a full recovery.

Olsen suffered a traumatic brain injury during a clash between protesters and police. Videos of the incident show officers lobbing tear gas cannisters near Olsen, but police have not said what caused his injuries.

The incident left Olsen’s speech impaired. In the interview, Olsen struggles to speak clearly and wears a neck brace.

Olsen said he went to Oakland on the night of Oct. 25 after hearing Occupy Oakland's call for people to join their protest. Earlier that morning, police raided the group's city hall encampment.

Before he was hit in the head, Olsen said he was off to the side of the crowd, texting a friend.

“Next thing I know, I’m down on the ground, and there are people above me trying to help,” Olsen said.

He said he wondered what the fuss was about until someone asked him his name, and he couldn’t speak.

“I couldn’t answer them, I don’t know if I couldn’t recall the answer or couldn’t spit it out,” Olsen said. “That’s when I knew yeah, it’s time to let them take care of me.”

Olsen said that when he awoke from his coma, he was unable to talk. But after a month of therapy, much of his speech has returned.

The Oakland Police Department continues to investigate the incident. But Olsen said investigators haven't interviewed him, and he doesn’t know when police will complete the investigation. 

“It’s been over a month, how long does it take to see who fired this at me?” Olsen asked.
