The first sentence is literally:

"The problem is that only a tiny percentage of harassers and rapists are ever convicted. The court -- rightly -- sets a very high bar to conviction, and police and prosecutors often won't even attempt it unless the evidence is overwhelming.".

First, its a poor place and topic for sarcasm (it just an observation, i'm not against it, i do have good friends like that) but more than that, GP actually adressed the point you're trying to highlight in his first sentence.

That wasn't being disputed. It does mean that, in the real world, a lot of victims will never see justice until there's overwhelming evidence, if ever.
