Nolle prosequi="to be unwilling to pursue." The declaration may be made because the charges cannot be proved, the evidence has demonstrated either innocence or a fatal flaw in the prosecution's claim, or the prosecutor no longer thinks the accused is guilty, and/or the accused has died. Link

This wimping out by the prosecution is bizarre considering that in the first assault she 1) instigated a fight 2) committed assault with her fist and an umbrella(what are you The Penguin?) 3) pursued the victim and committed assault again. Once the crime is out in public view, it shouldn't matter if the victim refuses to press charges as long as there are other witnesses. Maybe no one came forward to testify.

I believe that's how some (most?) states handle domestic violence cases.
Even if the victim doesn't want the perp arrested, the "state" becomes the complainant and off to jail they go.
