Also keep in mind, even if Trump isn't impeached, Trump won't be president indefinitely. If he loses reelection in 2020 or remains in office until 2024. The moment he leaves office the FBI can arrest him and charge him then. Providing of course his crimes dont have a statute of limitation.
Also, American law makers need to drop the nonsense idea that a sitting President is above the law. There is no specific law that says a sitting President can't be charged. From what I've read, this idea is based on inferred understanding and precedent. It's not cold hard law. All it takes is the judicial system growing a damn spine and charging a president. Our country isn't supposed to have an aristocracy, but this idea that Presidents are above the law is exactly that. Aristocratic BS.
And this jury situation is a prime example of why juries for any sort of major financial crimes and complicated matters shouldn't be made up of average americans. They arent remotely qualified to determine the outcome of cases like this. Only qualified people with a background in finances and the law should be on a jury for a case like this.
