How do you fix this?

Jodi Arias may be getting a new trial due to prosecutorial misconduct. There have been case in the past where a conviction was tossed for that very reason, and a new trial blocked. Is that fair? There is no doubt that Jodi murdered her former boy friend. The prosecutor wanted the death penalty and did not get it. most of the misconduct is in dealing with disqualifying jurors who opposed the death sentence.
Jodi was a good looking woman, and it is hard to get a death penalty from jurors who get hung up on the fact that beautiful woman can be just as poisonous as ugly men.
My personal opinion is that sentences should be handled by the judges, never a jury. Set guidelines and standards and require the judges to follow them to a tee. The same crime in LA should merit the same sentence as one done in Sacremento and it should not matter if the perp is old, young, male, female, black Asian white or a green midget from mars. In fact, to make it fair, have the sentence review done by a judge unfamiliar with the case, base it solely on the evidence and the verdict handed down by the jury. First degree murder? a needle, a rope, or a bullet, dead is dead.
Now, it is possible that an appeals court in Arizona will nullify this conviction and possibly a crazy woman walks free to the detriment of humanity.
No, just NO! lock up the prosecutor. If Juan Martinez s guilty, stick his sorry ass in general population for twenty years to be ass raped by every felon in the big house on an hourly basis. Let that be the message to rogue persecutors. Suspend his law license? Why bother? Hos political buddies will keep him in politics just like Barry and Mike who "surrendered" their licenses for reasons not public then turned that into occupation of the White House and lucrative deals worth millions.
The other option I would support is dropping them in the ocean near Bikini Atoll along with thousands of their ilk, assign a Navy destroyer to patrol close by and shoot to smithereens anything that leaves the island.
