It is, but not in the way you think. We've got Clinton, who committed no crimes, but is still treated as a criminal by many. OTOH we have Trump who has definitely committed crimes and continues to escape justice. We know, for example, that Trump was involved in fraudulent campaign donations and spending in order to cover up his affairs. But he's not being prosecuted for that. We also know that he committed obstruction of justice, and yet he's not being prosecuted for that.
