People are wrongfully imprisoned for crimes that they didn't commit too. Does this knowledge influence how you felt about Charles Manson (or insert your favorite evil person) being found guilty? Of course not. You had no reason to suspect that he wasn't guilty.
My point being, what evidence do you have that these college kids are any less American than the White Nationalists or hate groups/cults that have plagued our society for decades? Not trying to pick on you Dave, but "othering" or setting apart these college kids as foreigners too closely resembles a path towards xenophobia that only leads to more problems. Yes, college aged kids get visas to study in the US, but knowing firsthand that many college campus are deeply split on this issue, these are definitely mostly American college students on either side, supporting Isreal or Palestine. Half of college campuses in the US are not foreign born students.

Let's not call for deporting people we don't know not to be American citizens.
