I've made many of them to be liars on the witness stand. It is usually pretty easy to do since the average cop statement will have at least three or four lies in it.
You must be a better attorney than me. When I was doing criminal defense I had a hell of a time proving the cops were lying on the stand.
It depends doesn't it? DWIs are the easiest because the statements all say the same thing, but there is always a DVD. So the jury can see that you're client wasn't swaying and wasn't slurring his words and so on and so forth. That is why DWIs only have a about a fifty percent conviction rate for those that actually go to trial.
