The Buffalo incident offers a vivid example of why police records should be considered unreliable. Where are the "good cops" among the 20 or so in the video who had the opportunity to speak up, but in practice chose to maintain the blue wall of silence?
"The union representing Buffalo police officers told its rank and file members Friday that the union would no longer pay for legal fees to defend police officers related to the protests which began Saturday in downtown Buffalo and have continued on and off, according to one source. The union is upset with the treatment of the two officers who were suspended Thursday."

If you volunteered to program the Foo system at your job, and your company announced that you would be individually liable for any losses anyone suffered for your further work on Foo system, would you keep volunteering to program Foo or would you look to work on other projects?
Really the issue is one of process. Was shoving the guy to the ground and leaving him there a normal procedure for dealing with the alleged offense? If so, it's the department's fault and the superiors are negligent. If not, they failed to follow process and caused a death, so they should be individually liable for assault charges.
Future allegations may or may not be true. Even officers who follow all procedures want legal defense against false or questionable accusations.
