The case was so weak that the local Sanford District Attorney refused to bring charges against Zimmerman. That is why, on the orders of the governor, an outside District Attorney, Angela Corey, had to be brought in to handle it.
Sanford Police Chief Bill Lee was fired because he also refused to charge Zimmerman with a crime.
Anybody who followed the trial with even a minimum amount of attention could tell that there was no way the prosecution could prove beyond a reasonable doubt that Zimmerman wasn't acting in self-defense. The story argues that they didn't even think Zimmerman committed a crime, which also seems likely.
These people just wasted millions in taxpayer dollars, and held in prison a man who wasn't guilty of a crime, only to (as the prosecutor said after the case:) “put the facts out there.”
I'm not sure that blatantly wasting taxpayer money is an offense that can get someone disbarred (I doubt it is, unfortunately). It should be, and all who pushed forward with this case (that are lawyers) should be disbarred.
