A timely release of Denver jail video in the death of inmate Michael Marshall.

Whatever you think of the district attorney’s decision not to prosecute deputies involved in the jail death of inmate Michael Marshall — and we’ll want to reflect on the full video before reaching any firm conclusions ourselves — you’ve got to credit Mayor Michael Hancock’s administration and the DA’s office for putting a priority on getting the investigation done and releasing the video.

They were prodded of course by demands from the family and their supporters, as well as requests by the media, but release of the video was much faster than it had been after the jail death of Marvin Booker several years ago.

In that case, video was not released until eight months after the DA announced he would not bring charges against the deputies. Instead, the city waited for an internal disciplinary investigation by the safety manager.

This time the video was released to the victim’s family the same day as the DA’ s announcement.

Let’s hope this becomes the new normal for any case that spurs legitimate public concern. Investigate the incident as quickly as thoroughness permits and then release relevant video. It’s a new era and the public expects a new level of transparency.

Marshall was restrained by deputies on Nov. 11, choked on his own vomit and died nine days later. So the police investigation and DA review of the case took two months — a period, it’s worth noting, that included three holiday weekends.

DA Mitch Morrissey does not appear at all conflicted in his statement explaining the decision not to press charges. In fact, he goes out of his way to characterize the deputies’ actions as legitimate under the circumstances.

“It is important to note that there were no punches, kicks, strikes of any kind, or any impact force used to control Mr. Marshall throughout this incident,” his statement said. “No choke holds or carotid restraints were used. Tasers were not used. The physical force used by the deputy sheriffs during this incident was applied by holding Mr. Marshall and by preventing him from getting up.”

Any reasonable assessment of the video will have to take Morrissey’s nine-page statement into account, with its description of various witness testimonies. But it’s worth noting that a decision not to press charges doesn’t always mean the city is off the hook.

Although no charges were filed in the Booker case, either, the city ended up losing a $4.65 million civil suit.
