It's not about the warrant (which was mentioned just to reinforce the lack of oversight law enforcement has when it invades people's privacy) but the massive assymmetry here and the person I'm responding to compared this situation to the rights Americans have.
Normal citizens can't get full no fly zones and are subject to even more invasive tactics. The comparison to normal citizens highlights that what was done here was far in excess of what is done for normal citizens and seems counter to their overall argument.
