I bet there are many cops who have had complaints filed. jmo
According to
this article in WaPo
"about 13 percent of Ferguson’s officers have faced excessive-force investigations. ...the National Police Misconduct Statistics and Reporting Project, funded by the libertarian Cato Institute, estimated on the basis of 2010 data that about 1 percent of U.S. police officers — 9.8 out of every 1,000 — will be cited for or charged with misconduct. Half of those cases involve excessive force."
So, about 1/2 of 1 percent of U.S. police officers have been cited for or charged with excessive force. And about 13 percent of Ferguson's officers have faced excessive force investigations.
This suggests to me a few things:
First, the people of Ferguson aren't particularly reluctant to file excessive force complaints.
Second, the FPD has serious systemic problems.
Third and finally, if DW had made a habit of using excessive force, it's likely there would have been one or more complaints against him.
IMO, the FPD badly needs top-to-bottom reform.
Also IMO, DW was not one of the bad apples, and was completely justified in shooting MB. I'm open to revising that opinion if credible evidence to the contrary comes to light, but that's what I believe right now, based on the level of credibility I give to the various bits of evidence of which I'm aware.
