Yep. I was acquainted with a green card holder from Serbia who got accused of a war crime. He eventually was stripped of his green card and sent to Croatia to face a trial there. The basis was that he didn’t tick the “I am a war criminal” box on his green card application. He submitted to a plea agreement to be incarcerated for not ticking the box for 2 years and then was deported. (This happened back in 2015 under the Obama administration.)
Croatia gave him a fair trial and found him not guilty. Despite that he can’t ever come back to the U.S.; this situation is analogous to what the protester from Columbia is facing. Basically, USCIS can decide you lied on an application about a crime they think you committed, without actually being convicted of that crime. (Or in the case of Slobodan Mutic, eventually being found not guilty.)
