There's a difference between supporting law enforcement generally and supporting specific law enforcement efforts. I personally want my local law enforcement to be fast and effective because I want them to keep me safe from crime, but I don't want them to violate my or other people's rights in the process of keeping me safe from crime. So, in that vein, I might not object to police gaining a specific new tool but I would object if I found out that the police were misusing it somehow. The employees objecting to Palantir's work with ICE are probably not objecting to cooperation with border enforcement on the principle that border enforcement is immoral generally, but that recent activities by border enforcement are immoral. If it weren't for the internment camps at the border, we probably wouldn't be hearing about this. There's a broader discussion about the 4th ammendment and Palantir's effect there, but I don't think that this particular protest is about that.
