Any quick convictions would be pardoned by Trump, so investigations will have to do for now until Democratic President takes office.
Not if they impeach his ass. He has ordered the murder of innocent people at sea because, without evidence, he say they're running drugs. His military even murdered two men clinging to the wreckage of their boat by ordering a second attack on them while they were helpless. That is, at minimum, a war crime. So is the double tap strike on an Iranian bridge. American forces blew up the bridge then, an hour later after emergency workers were there to help survivors, fired a second missile.
If these aren't high crimes and misdemeanors then I don't know what is. Yes, Vance is a putz and will probably not be much if any better, but we NEED to hold Trump accountable for his crimes. It is an absolute imperative if this nation is to ever recover from this era.
