The DOJ under Biden set the standard for vindictiveness. It is disingenuous at best to act shocked when Trump's DOJ acts in the same manner. It is the slippery slope at work. Regardless, nothing will happen and any attempt at making something happen will be shot down in the courts
That is demonstrably false. If Biden's DOJ was so focused on being vindictive, they would have (and honestly, should have) launched their investigation into Trump's election denial campaign that culminated with the January 6 insurrection a hell of a lot sooner. And, let's face it, he would have likely been convicted, according to Jack Smith (who is a veteran prosecutor, so he probably knows how to win cases). The stolen classified materials trial should have happened a lot sooner as well, if not for the fact that Trump appointee Aileen Cannon slow walked the case to such an extent that he is basically off the hook now. Now, maybe if the January 6th case started a hell of a lot sooner, the documents case would have been settled a lot sooner (the reason Donny boy was charged was because he actively sought to keep the documents and hide. If he turned them over like he was supposed to, there would've been no charges).
Now, for the other cases you're probably crying about: They were in at the state level. The conviction, I understand why some people are upset about that, they think that his fraud and lying about the value of his properties was basically a victimless crime. And, on some level, it was. But, the fact that he was able to secure millions in loans that he likely wouldn't have been eligable to get (or at least get at the rate he did) means that maybe other legit and worthy borrowers couldn't get access to that capital.
And in Georgia, let's just say that Trump likely broke election laws in that state. So, he likely should've faced consequences.
So, you can cry all you want, but the reality is Biden's DOJ was not vindictive or making shit up. They had legit cases, but Garland erred on the side of political caution and didn't immediately start looking into these cases. I really hope who ever the next President is they will do a thorough investigation into Trump and his shady business deals. That is the only way to rebuild trust in the institutions that Trump has so magnificently damaged.
