MILWAUKEE (CBS 58) -- A deadly police shooting on Highway 175 is raising questions about Milwaukee Police Department's (MPD) body camera policy. The sergeant who shot and killed a driver Monday night, Nov. 2, was not wearing a body camera.

Current MPD policy does not require sergeants to wear them. That’s not unique to just the Milwaukee Police Department. National experts say police departments across the nation do not have sergeants and other upper ranking officials wear body camera.

Despite no bodycam, in a press conference, Milwaukee Police Chief Jeffrey Norman says there’s still other video of this fatal incident.

On Monday night, State Highway 175 near Lloyd was shut down in both directions after Milwaukee police say a sergeant shot and killed an armed wrong-way driver.

“He was outside the vehicle, we don’t know the extent of where that contact with the sergeant happened,” said Chief Norman.

Investigators say a sergeant in a marked squad saw a truck make a U-turn and drive south in the northbound lanes. Police say when the sergeant approached, the driver showed a gun. That's when the sergeant fired, killing the driver at the scene. The driver's gun was recovered, but police don't know if it was fired.

“The subject does not need to fire the gun in order for the sergeant to have full justification,” said Timothy Dimoff, a national police procedures expert with over 20 years of law enforcement experience. “If you feel a person can potentially cause serious physical harm or death to you or to others, the sergeant has full responsibility, obligation, and has the full legal right to defend himself and others."

There is no body camera video of this incident because MPD does not require sergeants to wear any. Dimoff says that’s standard procedure for many police departments across the nation.

“Many police departments do not have their management or their higher-ranking personnel – sergeants, lieutenants, captains – with bodycams,” said Dimoff.

Dimoff says there’s a few reasons why. Sergeants are typically not the first ones on the scenes and typically other officers who do wear bodycams are present.

“Their job is to monitor it, to come to a scene if requested and also automatically to go to a location if their monitoring says this is escalating and they need to have a supervisor,” said Dimoff.

Does this mean policy should change because of this incident? Dimoff says that’s unlikely.

“So far statistically, it’s just not happening very often of this unique incident,” said Dimoff.

Chief Norman says despite not having body camera from the sergeant, there are other multiple sources of video MPD is looking at.

“We don’t have all the full details on that. We’re still looking at a couple different videos and also some interviews so, it’s still ongoing,” said Norman.

Police said video related to the incident will be released in 15 days according to department policy.
