Officer William Porter testified Wednesday at his manslaughter trial in the death of Freddie Gray. Here are some of the questions he was asked and his remarks:

— Why does Porter say he didn't call an ambulance for Gray after checking on him during the police van's journey?

"He never made a complaint of pain or an injury. In order to call for an ambo, I need age, sex, location and complaint of injury. He wouldn't give me a complaint of injury."

— According to Porter, did Gray ask for medical attention or did Porter suggest it?

"I offered it to him and he said, yes, he needed it."

— What does Porter say he told van driver Caesar Goodson, who faces the most serious charge in Gray's death?

"I suggested Officer Goodson to take him to a medical facility or a hospital. I cannot order Officer Goodson to do anything."

— What kind of distinction does Porter make between driving a prisoner to a hospital in a police van versus calling an ambulance?

"You call for an ambulance if you have a medical emergency."

— What does Porter say happened after he saw Gray unresponsive in the van at the Western District police station?

"It was a very traumatizing thing for me, also. Knowing him from the neighborhood and calling his name, being on the hospital detail and seeing everything they'd done to him."

— What does Porter say is the risk of a prisoner grabbing an officer's gun if the officer tries to buckle a prisoner's seat belt?

"In academy, and through my experience and training as an officer, even the most docile detainee presents a risk."

— Does Porter think the Baltimore Police Department has a "don't snitch" culture?

"I'm actually offended you'd say something like that."

— What is Porter's response to the statement that he failed to protect Gray's life?

"Untrue."
