> aren't immigration laws there for a reason

Right, the problem is you're assuming immigration agents are following the law. You need to alert people of where they are to protect them. People who are actually here legally are being arrested, waiting for them outside courtrooms. There have been several cases of actual American citizens detained illegally based on racial profiling. There's no proper due process. Additionally, the treatment of those who are detained is very inhumane, using tactics to induce fear.
