A State Department special agent accused of murder after he shot and killed a man at a Waikiki McDonald's in 2011 has taken the stand in his own defense.
Christopher Deedy was sworn in and began testimony Tuesday, one month into trial in the killing of Kollin Elderts of Kailua.
Deedy's defense lawyers contend that he was acting in self-defense and identified himself as a law enforcement officer during the deadly altercation in the early morning hours at the crowded restaurant.
Prosecutors have argued the shooting was caused by intoxication and Deedy's inexperience.
Deedy, from Arlington, Va., was out bar-hopping with friends. He was in Honolulu to help provide security for the Asia-Pacific Economic Cooperation summit.
Elderts died of a single gunshot wound to the chest during a fight with Deedy.
Late Monday, former federal law enforcement trainer Ken Amiano testified that the thrust kick you see Deedy doing on the surveillance video is a common training tactic.
"We do train the agents, if you're in a situation where somebody is trying to cause you severe bodily harm, or kill you, cause your death, you have to use whatever means necessary to stop it," said Amiano.
Amiano says federal agents are trained to use physical force depending on the situation. He is expected to be back on the stand Tuesday.
