And that "entire point" is historically incorrect in the United States. There is a long, long, LONG history of the Department of Justice investigating and prosecuting members of the administration that technically runs it.
That your point seems to be correct now, in the most corrupt administration of the modern era, is something that is notable and worth discussing. It's certainly not something to sweep under the rug with a both-sides-ist dismissal.
(It's also tautological: I mean, of course they wanted to prosecute them. They were criminals and prosecutors prosecute criminals, definitionally!)
(And also also, it's an Occam's violation: the simpler explanation is that they were just treated like criminals and not that they were double-negative enforcement actions by a corrupt regime.)
And even when cases are brought, the DoJ needs to defend them. See a number of cases that were very far along in the court system that the Biden administration was pursuing, that the Trump DoJ just quit defending. They simply no longer have a lawyer, and functionally cannot proceed.
I do not see that here for the current admins demands for diversity.
