Yes, the Abrego Garcia and Öztürk detentions are two very newsworthy cases that have actually reached the point of a final judgement in the district courts, as opposed to "merely" preliminary injunctions against the government.

(It's also worth noting that almost none of the government's appeals to their losses in preliminary injunctions have been on the merits as to whether or not their actions were legal, but rather on the grounds of "no one should be allowed to challenge our actions," which has also been a fairly losing argument for everybody except SCOTUS.)

>if that is even possible

yes.... any administration can be found guilty of violating law, and should be dealt with accordingly.

> Has the Administration actually been found guilty of violating the law - if that is even possible.

Obviously administrations can violate the law. Otherwise this is just an autocracy with term limits.

>Allegations aren't evidence

Allegations are literally evidence. "He attacked me" is an allegation of a crime and is evidence that would be used in conjunction with other evidence to prosecute said crime.

Evidence is evidence - of which there are enormous amounts of.

Are you expecting the administration to prosecute itself?
