Authorities say Collar had taken LSD and threatened the officer. Beasley said forensic scientists have not completed a toxicology report on drug use.
He said the video does not contain audio, but it was obvious Collar and the officer were talking.
"The fact that he came to the police station indicates that he was not necessarily looking for trouble. In fact, I think he was looking for help," Beasley said.
Collar's parents, Reed and Bonnie Collar, accompanied Beasley to the news conference, but did not comment. The sat in chairs, holding hands, bowing their heads and nodding occasionally. Beasley said they have been praying for the officer, but hold the university accountable for training its officers properly.
Beasley said his law firm will complete its investigation before the family makes a decision about whether to sue the university, but the family's ultimate goal is to make sure policies are in place to keep the same thing from happening to another student.
