Quickly, I'll add that if, for instance, someone accused of providing misleading information was trying to defend themselves, all they would have to argue is that they did not do it on purpose. The prosecuting party would then have to prove that it was done deliberately. If, however, the prosecuting party determined that a volunteer simply made a mistake, they could drop the proceedings against that person. Volunteers are protected against this kind of thing.
To my mind, this unnecessarily adds to the burden of proof the prosecuting party has to satisfy, making it more difficult to prosecute someone who knowingly provides false information.
