Why would the contents of that sever be prosecuted, it was never breached and under the control of the secret service 24/7? They have done numerous investigations and determined that there was nothing to prosecute Hillary for. If there was ANYTHING at all they could charge Hillary for, they would have done it already, as GOP would love to do so more than anything else. They just don't have anything to do so. They can't burn down her house without burning down their own, as those accusing her have done far worse than anything she ever did for the most part. Trump's entire administration has used more unprotected devices, emails and exposed more classified information than ANY other, so if they were going to go after Hillary, they would have to take themselves down with it, with Trump being the worst offender of them all. Trump literally fired his security guy that was supposed to secure his phone and didn't replace him so he didn't have to secure his phone for like a year while still using it.. LMAO
However, we have an additional long list of actual crimes to prosecute trump for, ONCE he is no longer in control of the FBI and DoJ and can obstruct investigations. Whether or not they choose to do so is the question. Just because there is abundant evidence, and probable cause for arrest and prosecution in the US, we have no law that says they have to do it. That is why criminals walk ever day, as they are not required to charge criminals regardless of how much evidence they have.
Sadly in the US, however, Presidents, congress, secretaries of state ect are legally allowed to engage in warmongering and warmongering is completely legal for them to do so, so there is nothing to be prosecuted for there. If it were illegal, we would have to arrest every US president, secretary of state and congress that ever existed, including Trump and his goons, as they all did this. They are the ONLY ones in the country that are designated to be allowed to do this apparently.
