all lawyers should be disbarred
"Agreed, the lawyer should be immediately disbarred."
If the case was dismissed with prejudice, the lawyer should certainly be sanctioned. Disbarring the prosecutor, however, is as inappropriate a remedy as dismissal with prejudice would be.
If the facts are as we surmise (i.e., not dismissed with prejudice), I would recommend something like either an intraoffice suspension if I were the chief prosecutor or a month's suspension if I were the bar committee reviewing such an infraction. You have to know with publicity this sort of thing will never happen to this lawyer again. But then, I'll never be on a bar committee for the very reason that I WOULD be harsh about it compared to other folks in the legal community and there is no way a bar committee would EVER disbar a lawyer over something like this, at least, not standing alone.
If the case was dismissed with prejudice, however, and I was the chief prosecutor, this assistant would be canned, and if I were on the bar I'd suspend him from the practice of law for at least two years. People screw up, and this screwup would deserve punishment, but it's not like because this girl was allegedly (this does seem to be a pretty 'allegedly' case, if you read between the lines) raped and the prosecutor screwed up that this one should lose their livelihood forever. Suspension would be a big enough black mark on their record to overcome. A bar committee probably wouldn't disbar an attorney over this, even with prejudice.
