MacWilliams faces charges stemming from an investigation by the Independent Investigations Office, which took over the case after the shooting of Mehrdad Bayrami on a paved pathway outside the casino on Nov. 8, 2012.
Police responded to reports of a distraught man with a gun in the parking lot of the casino. After a lengthy five-hour standoff during which police could be heard imploring Bayrami to drop his weapon, he was shot.
MacWilliams was supported by dozens of fellow police officers outside B.C. Supreme Court on Thursday.
Many officers wore blue wristbands that bear MacWilliams' badge number. Delta police say they have sold more than 2,500 in the last month at $2 each.
A Dec. 4 Facebook post to Delta police department's page explains that "the bracelets were designed by our Police Association as a way for us to show our support for Cst. MacWilliams and honour our core values."
MacWilliams, who is currently on bail, is on paid administrative leave.
His next court appearance is set for next month.Suggest a correction
