Standing in front a row of people holding signs that spelled "practice peace", Edwards said: "In 28 years of law enforcement, I have seen a lot of hate. I have seen a lot of revenge. I've seen a lot of anger. What I saw, particularly from the Sikh community this week was compassion, concern, support.
"What I didn't see was hate. I did not see revenge. I didn't see any of that. And in law enforcement that's unusual to not see that reaction to something like this. I want you all to understand how unique that is."
At the FBI briefing on Wednesday, Carlson said Page had not come to the attention of federal officials before Sunday's incident. She said investigators were interviewing dozens of people who knew Page, in their attempts to determine a motive for the attack, which the FBI has classed as an act of domestic terrorism.
Page had a record of minor alcohol-related crimes in Texas, Colorado and North Carolina. He was demoted during a stint in the army for getting drunk on duty and going absent without leave before he was discharged in 1998.
After the army, Page drifted between jobs and played in white power bands. Sometimes he performed with a Nazi swastika hanging behind the drummer. His first band, Definite Hate, produced an album called Violent Victory with a cover design of a white fist punching a black man in the face.
The fist is tattooed with the letters HFFH for "Hammerskins Forever, Forever Hammerskins" after a national skinhead organization.
Page stopped showing up for work in July. He visited a gun shop and, after clearing background checks, bought the gun he used in the shooting.
His girlfriend, 31-year-old nursing student Misty Cook, was arrested on a provisional charge of being a felon in possession of a firearm, South Milwaukee police said Tuesday. The FBI said Wednesday her arrest was not linked to Sunday's shooting.
