Well, no that's a little different. If one out of thousands of police organizations were corrupt, that would offer little evidence that the average one is.

If one out of 5 acronym agencies is corrupt, that's a 20% corruption rate.

Now of course one incident doesn't prove a whole organization is bad. But it does show the processes used by that organization have insufficient oversight to prevent it.

Moreover, it's not simply one case. Yes, the comment brought up an isolated case, but there are many more known cases, and I'm curious how many unknown cases there are....

I feel like your arguments have been willfully oversimplifying and I question what your dog in this fight is.
