ICE has been regularly overstepping its bounds and going after people in ways that impact our legal system's ability to function. This is a terrible precedent to set for no other reason than it impacts the rule of law. If people who are accused of crimes can be disappeared without a trial, just for showing up to court, what incentive is there for anyone to go to court? They are literally ignoring the "innocent until proven guilty" that is critical to the rule of law.
If you take away people's ability to get justice within the system, you are making it inevitable that they will go outside the system to get justice.
