The problem is - who should be punished for gathering the illegally obtained evidence?
The policemen who physically gathered the evidence?
The lawyers who signed off on the gathering?
The officers who signed off on the gathering?
The politicians who pushed for a case to be made?
All the policemen who were involved with the case?
It's a tricky situation, because what is to prevent A from getting B to take the possible fall, by telling B to go pick that thing up?
What I'd like to see is somewhat similar, but with clear lines of responsibility.
The prosecutor in charge of the case is held in contempt of court for 10% of the maximum penalty possible for the crimes, but no less than 7 days (no pay etc), plus a fine equalling twice the salary that would have been earned in the time. Same for the lead officer/detective on the case.
The prosecutor's boss (DA/AG etc) gets 5%, but no less than 7 days (no pay etc), similar fine. Same for the similar position in the police's ranks.
Any public officials who have provably pushed for the case, gets 3%, but no less than 7 days (no pay etc), similar fine.
Not sure what kind of punishment would be fitting for the policemen, CSI techs etc. who gathered the illegal evidence though. If they planted evidence or gathered it in knowingly illegal ways, they should obviously go to jail, but the problem comes when they gather evidence in good faith, that later turns out to be illegal. I don't want to punish them for simply doing their job in good faith.
