As much as she richly deserves jail time, it's not the president's job to make that call.
I guarantee that if Trump raised this issue publicly (either now or after his election, should that happen), Madame Clinton's lawyers would surely use that in her defense in claiming that because of Trump's "prejudicial remarks", that she can't possibly get a fair trial.
Hopefully, Trump's too smart to fall into that trap.
Yes you are probably right.
