Two of the officers who died were from the Baton Rouge Police Department: 32-year-old Montrell Jackson, who had been on the force for a decade, and 41-year-old Matthew Gerald, who had been there for less than a year. But only a week before his death, he wrote a heartbreaking and prophetic Facebook post begging for peace in his community. We also continue to grieve for the families of Alton Sterling in Baton Rouge, Philando Castile in Minneapolis, and all who have suffered because of violence.
"I'm exhausted physically and emotionally. The city MUST and WILL get better", Jackson wrote.
He continued, "These are trying times".
Jackson leaves behind a wife and four-month-old son.
Asked whether he believed Long had drawn the police officers to the scene, he replied: "No doubt in my mind".
Despite his disappointment, Jackson had remained optimistic for the future and offered words of encouragement for those who needed it. "We as a nation have to be loud and clear that nothing justifies violence against law enforcement", Obama said, speaking from the White House press briefing room. The gunman opened fire after police arrived at an Airline Highway gas station in response to a call about a suspicious man carrying an assault rifle.
A marine from 2005- 2010, Long rose to the rank of sergeant and served in Iraq, earning several medals, including one for good conduct, and received an honourable discharge.
Officer Jackson had written a Facebook post expressing how hard it was for him to be both a black man and a police officer.
One of the three police officers killed in a sniper attack in Baton Rouge, Louisiana, on July 17 penned an emotional Facebook post about two weeks before he was killed.
Although he was believed to be the only person who fired at officers, authorities said they were unsure if he had some kind of help. "Attacks on police are an attack on all of us and the rule of law that makes society possible".
Donald Trump on Monday seemed to accused President Obama of being partially responsible for the recent murders of police officers and for fueling an anti-police sentiments. L.J. McKneely said. After leaving the military, he finished police academy a year ago and continued to serve as a Baton Rouge officer.
