I get where you are going, and in principle I agree. But I think it is much more nuanced than what you have written.
If I am understanding you correctly, you think Trump needs to sort the J6 incarcerated based on likely guilt and provide political support to those deemed not/less guilty. I have no idea what that would look like.
Trump’s only power at this point is to expose what is going on. Saying that he should clean it up, essentially, “fix it”, may sound good. But it seems to me his options are limited, and good options are fewer still.
He needs to admit that some of the J6 prisoners deserve to be in prison, because some of them do. Taking a dump on the Speaker’s desk, as has been reported, is not acceptable behavior, no matter how much you may dislike the Speaker at that time. Admitting there was some actual lawlessness would help get the issue properly resolved for everyone, because most people just want the honest truth.
He also should be trying to defend those who have been indefinitely incarcerated for simply trespassing, if that has in fact happened. Or has it? Maybe it’s just a wives tale. We won’t know until those incarcerated are reviewed by crime type, criminal history, etc.
With Trump unwilling to even turn over a single leaf to find the truth of who these people are, we’re left having to assume most of them might actually deserve to be behind bars. They still don’t deserve to just rot there, without a speedy trial, but maybe they are all guilty of something if no one will identify or help them. And Trump not helping them is another indication maybe they all are guilty of crimes, after all.
