This is utter nonsense. You could file an "information" for a non-capital offense, but you are trying to say the man was murdered, and you are in Florida, this would not apply and you would never be able to charge that without a Grand Jury.
And pretending that an Information wouldn't require you to meet the elements of the crime is beyond irresponsible. No ethical prosecutor even in Florida would charge crimes without evidence that meets the elements of the crime.
Seriously... this is disturbing. If you were a prosecutor and regularly just "signed" Informations just because you felt good about things you were not just a bad prosecutor, you were acting extremely unethically.
