People should not be arrested for peacefully protesting, I would say, rather than implying giving in to mob rule by never arresting someone just because they are protesting. (That would be fun, “hey Mr. Policeman, I see you are about to arrest me for stealing this car but I’m in the middle of a protest against theft laws, so you can;t touch me.”)
The question was loaded from the outset:
If there’s a Latino undocumented person in that group who’s arrested for protesting, do you think that person should be deported?”
Firstly, lay the trap of implied racism, which the respondent fell into. I suggest his answer would be identical if the question had instead been:
If there’s an undocumented person in that group who’s arrested for protesting, do you think that person should be deported?”
There is also the attempt to imply that people are arrested simply for protesting, rather than rioting, vandalising, theft, beating up old ladies in the street and all the rest that’s been going on. The question, removed of its traps, should have been:
If there’s an undocumented person in that group who’s arrested for their actions while protesting, do you think that person should be deported?”
There is no valid reason to arrest just for legally protesting peacefully. There can be all kinds of reasons to arrest protestors who are not peacefully protesting.
The question then comes: if you have someone protesting in your country, regardless of proving any illegal action other than that they should not even be in your country, do you take appropriate action. Surely, anyone who believes in democratic law will say that such a person should be dealt with for the illegalities they are committing, rather than just be let loose and .. what .. picked up sometime later when they are not in a protest? Allowed to continue breaking the law?
