BATON ROUGE, LA. (CBSMiami/AP) - Online posts may give a deeper look into the mind of the man who shot and killed three law enforcement officers in Baton Rouge, Louisiana over the weekend.

In online posts, a man using an alias of the Baton Rouge shooter says protests alone don't work, and people must fight back after the deaths of black men at the hands of police.

Documents show that gunman Gavin Eugene Long sought to change his name last year to Cosmo Setepenra. A website using that name links to online books about nutrition, self-awareness and empowerment. The man describes himself as a "Freedom Strategist, Mental Game Coach, Nutritionist, Author and Spiritual Advisor."

In a video posted July 10th, the name says he's speaking from Dallas after the fatal attack on police officers there during a march over the deaths of black men at the hands of law enforcement. The man also discusses the protests in Baton Rouge and what he perceived as oppression.

He says: "You've got to fight back. That's the only way a bully knows to quit."

In an earlier video, the man says that if anything ever happens to him, he doesn't want to be linked to any groups, and mentioned once belonging to Nation of Islam.

Long, a former Marine from Kansas City, Missouri, turned 29 on Sunday, the same day he opened fire, killing three law enforcement officers and wounding three others. Long was killed at the scene.

The shooting added to the tensions across the country between the black community and police.
