Baton Rouge gunman signalled 'horrendous acts of violence' in manifesto
The man who ambushed and killed three law enforcement officers in Louisiana reportedly called his actions a "necessary evil" in a handwritten manifesto that an Ohio man says was emailed to him by the gunman less than an hour before the shootings.
Photographs of the three-page letter show it was signed by "Cosmo", the first name of an alias used by Baton Rouge gunman Gavin Long, and the pictures were attached to an email sent from a Google address Long used.
In the letter, Long said he expected people who knew him would not believe he would commit "such horrendous acts of violence". He wrote that he viewed his actions as necessary to "create substantial change within America's police force".
The Associated Press obtained the photographs of the letter on Wednesday from Yarima Karama, a musician from Columbus, Ohio, who said he did not know Long personally but received several emails from him after Long began commenting on Karama's YouTube videos in March.
The AP was not able to conclusively verify that Long sent the photos himself from his Google account. Metadata from the three photos indicates they were taken shortly before 8am on the day of the shooting using a Motorola Android mobile phone, but both photos and time stamps can be modified. The photographs appear to have been taken from inside a car because a gear stick and a cup holder are visible.
Police have said officers first saw the gunman at a convenience store at 8.40am on Sunday. Within two minutes, there were reports of shots being fired. Police gunned down Long after he killed three officers and injured three others. It was his 29th birthday.
The violence capped two weeks of turmoil for Baton Rouge which began with the killing of a black man, Alton Sterling, during a scuffle with two white police officers at a convenience store. That shooting, captured on mobile phone video, provoked widespread protests about police treatment of the black community.
Karama said he provided a copy of the letter to FBI agents who interviewed him at his home on Wednesday.
The story about the manifesto was first reported by BuzzFeed.
Todd Lindgren, a spokesman for the FBI office in Cincinnati, said he could not respond to any questions about the case "due to the Baton Rouge matter being an ongoing investigation", and the FBI's New Orleans office also refused to comment.
Louisiana State Police Colonel Mike Edmonson said law enforcement officers found an array of handwritten documents in Long's car and a hotel where he was staying, but he did not know if the material included the letter Karama shared.
"It was all rants and raves," Col Edmonson said.
In the self-described manifesto, which was started off with the words "Peace Family", Long wrote about a "concealed war" between "good cops" and "bad cops", and said he felt obligated to "bring the same destruction that bad cops continue to inflict upon my people".
Long, a black military veteran whose last known address was in Kansas City, Missouri, spent five years in the Marine Corps. He served one tour in Iraq before being honourably discharged.
Before the Baton Rouge shootings, he posted rambling internet videos calling for violent action in response to what he considered oppression.
He did not specifically mention Baton Rouge or detail his plans for an attack in the letter.
"I know I will be vilified by the media & police," it read. "I see my actions as a necessary evil that I do not wish to partake in, nor do I enjoy partaking in, but must partake in, in order to create substantial change within America's police force, and judicial system."
Karama read the letter in a video posted on YouTube. He declined to provide the AP with copies of the other emails he said he received from Long or with additional technical information about Sunday's email that possibly could help the AP conclusively verify that Long wrote the letter.
Karama, who described himself as a hip-hop artist and community activist, said he provided other information about Long's emails to various news outlets.
"I'm about building my own brand at this point," he said. "I've given the information to who I need to."
