ICE is now a huge military force, with a budget bigger than the militaries of most nations. It isn't part of our national defense. It operates only within this country's borders. It does not track down drug cartels or violent gangs. It isn't looking for bank robbers, rapists, or murderers. It will now be receiving from Medicaid and the IRS information that used to be considered private and confidential. Ask yourself what history tells us about countries that have huge internal militarized police forces with operatives whose identities are concealed, arresting people without warrants, moving them to undisclosed locations, imprisoning people without trials, and accumulating vast dossiers of information on the entire population.
