The city of Baltimore is the city of Baltimore. It's run by politicians who make decisions based almost entirely on politics, public perception, and optics. It matters not how much hard earned tax dollars the politicians decided to try and placate the families involved, the courts (and facts) concluded no crime, no murder, no manslaughter. What's left is a tragic accident.
I'm guessing the Baltimore police have adopted new procedures for placing detained prisoners in their vehicles, to hopefully keep future tragic accidents from occuring
