He described Dorner as "a perfectly rational human being," "smart and insightful."
"Never anything that I experienced in a million years would lead me to conclude that this horrendous activity that he engaged in at this point was ever imminent or would ever be any type of concern," he added.
Dorner joined the Navy after college, receiving a commission as an ensign in July 2002. He trained in river-warfare units and and served a 2006-2007 stint in Iraq guarding oil platforms, according to Pentagon records. He held a commission as a lieutenant until February 1 and was rated as a rifle marksman and pistol expert, according to the records.
He enrolled in the LAPD Academy in February 2005 and spent four months on the streets as a trainee before being recalled to active duty for his stint in Iraq, police records state. In the end, the LAPD cost him not only his police job but his career in the Navy, he wrote.
"This is my last resort," he wrote. "The LAPD has suppressed the truth, and it has now led to deadly consequences."
