Where did the "multiple sting attempts" come from? (There is only one in the court documents - it wouldn't surprise me if there were others but this phrase suggests that you are privy to something that the rest of us are not)
Why was this specific officer subject to "multiple sting attempts", if that was the case?
Stuff like this doesn't just happen. Only plausible explanation is that there were a lot of complaints about that specific officer. Why complaints about that specific officer relative to others?
If you're going to present hypothetical arguments then I'll present hypothetical counter-arguments. The speeder who didn't get the speed bumped beyond 50 over, didn't get it bumped because it would look suspicious if that officer bumped all of his speeding tickets to more than 50 over.
There's no way to prove or disprove anything now.
With the sketchiness of what was outlined in that court document, I'm surprised he was charged at all.
