I am pretty sure Trump could pardon them just incase they were convicted. And the good examples of presidential pardons, are trying to correct the actions of our legal system when it failed to deliver justice; so anyone looking at the situation objectively would see it as correcting an error in our justice system. In any case, I think this would have zero effect on public opinion, the people that hate trump would still hate him, and the people that support him would still support him. I do think trump should have given them (and assange, and snowden) pardons, Im pissed he didn't. But nearly all my contempt is for the psychopaths that created this situation. I think its odd when people laser focus on Trump and refuse to address the source of a problem. Also if Trump supporters were thought of him as a messiah, they wouldn't have booed him at his own rally when he started bragging about how great the vaccines are, they did this at least twice.
