Former officer Devin Sparks and Corporal Randy Murr are testifying before the Denver Civil Service Commission this week.
In 2009, they were caught on camera beating Michael DeHerrera outside a club in LoDo.
The video started a debate over their discipline and solidified the reputation of the Denver Police as a force with some bad apples.
The civil service hearing is scheduled to last as long as to two weeks. It could be a month before a decision is made on reinstatement.
