Many people were taken aback by Denver Broncos linebacker Brandon Marshall decided to kneel during the national anthem before games early this season, to protest social injustice and show support for college teammate and fraternity brother Colin Kaepernick.  Something he continued to do for the first half of the season.

At the time, several people thought Marshall was anti-police, a notion he quickly dispelled. In fact, he pledged to communicate, work with and donate to community organizations, leaders and police officers (which he did).

This week, Marshall took his commitment a step further, joining the Denver Police Department at their training academy to go through several scenarios in their VirTra V-300 simulator.

The above video is but a preview, as the full session will premiere this Sunday on the Denver Police Department’s Facebook page.
