I don't object to enforcing borders but at what cost? That's the point here. A another example, the public objections to Flock cameras are not because we don't want to catch thieves, kidnappers, and other criminals, they are that we don't want to do that at the cost of having our movements tracked everywhere we go, and because when that tracking data exists, it is invariably, eventually abused.

Agreed, nobody’s arguing against enforcing border laws. That's a dishonest right-wing canard.

ICE is doing things that have nothing to do with them. DHS has subpoenaed tech companies to unmask people who criticize ICE online, and a federal judge ruled ICE likely violated the First Amendment by sending agents to warn a man over an email.

Hundreds of US citizens have been detained by immigration agents, and most were never charged with anything. Federal judges, including Trump appointees, have found illegal detentions THOUSANDS of times.

Enforcing the law is the OPPOSITE of violating the Constitution.
