These are all cases where crooked agents of the state either lied, manufactured evidence or otherwise conspired to intentionally frame someone they knew was innocent. Believing an unbelievable story of rape, a story which in itself will sustain probable cause for arrest if testified to under oath, is not actionable conduct. A prosecutor has that discretion by law and he even used a grand jury in this case. Further, a Judge found probable cause to hold the defendants on bail. The prosecutor and the County are covered here unless someone shows demonstable illegal conduct on the part of the prosecutor or police. This is what makes prosecutor power so dangerous in the wrong hands.
You might be right Joe, I hope you're not. It's just that I hope that ultimately it may be ruled that the conduct of the officials in this investigation has been so egregious that a reasonable person in a similar situation would not have acted in such a manner.
