So how is upholding the law, "abuse"???
The fact that both won in court against the police for tens of thousands of dollars is strong evidence that what the police did to them really was abuse. And the police were doing something other than upholding the law.
The fact that the police denied having video evidence that they in fact did have (which did not support their case) is further evidence that the police were simply in the wrong.
And finally, the fact that the "professional police review board" did not flag this as something that needs fixing is strong evidence that the review process does not, in fact, work.
