Highway Patrol season 1 episode 4
Episode title: Lookout
An uninvolved man happens to be in the company of two brothers who hold up a diner and kill its owner. Fearing the police and terrified of the vengeance he may expect from the criminals, he flees. As Dan searches for him, one man winds up dead, two critically wounded, and the man who a few short hours ago was an average law-abiding citizen is harried to the point where he is willing to shoot it cut with the police - until Dan manages to show the error of his ways.
