What a surprise. Chicago cops are actively sabotaging their dashcams:

Why are so many police dashcam videos silent?

Chicago Police Department officers stashed microphones in their squad car glove boxes. They pulled out batteries. Microphone antennas got busted or went missing. And sometimes, dashcam systems didn’t have any microphones at all, DNAinfo Chicago has learned.

Police officials last month blamed the absence of audio in 80 percent of dashcam videos on officer error and “intentional destruction.”

A DNAinfo Chicago review of more than 1,800 police maintenance logs sheds light on the no-sound syndrome plaguing Police Department videos — including its most notorious dashcam case.

Maintenance records of the squad car used by Jason Van Dyke, who shot and killed Laquan McDonald, and his partner, Joseph Walsh, show monthslong delays for two dashcam repairs, including a long wait to fix “intentional damage.”

On June 17, 2014, police technicians reported fixing a dashcam wiring issue in police vehicle No. 6412, the squad shared by Van Dyke and Walsh, about three months after it was reported broken, records show.

A day later, the same vehicle’s dashcam system was reported busted again. It took until Oct. 8, 2014, to complete repairs of what technicians deemed “intentional damage,” according to reports.

Just 12 days later, on Oct. 20, 2014, dashcam video recorded from squad car No. 6412 on the night Van Dyke shot and killed McDonald did not record audio. The video that went viral showing Van Dyke killing Laquan was taken from a different squad car, but it, too, had no audio.

Police officials quickly placed the blame on officers and shift supervisors responsible for making sure dashcam systems work properly before officers go on patrol.

In December, interim Police Supt. John Escalante warned the rank and file that they would be disciplined for failing to follow proper dashcam protocol. Weeks later, he followed through by hitting some officers and supervisors with formal reprimands and up-to-three-day suspensions.

“To boil this down, the Police Department will not tolerate officers maliciously destructing equipment,” police spokesman Anthony Guglielmi said.

Note that there are threats, but when the president of the local police union complains, he does not complain about actual punishments, just the threat of punishment.

This isn’t going to be fixed until someone from the outside excises the rot at the department’s core.
