AILA provides Know Your Rights handouts in several languages including English, Spanish, Chinese, Portuguese, Arabic, Haitian Creole, and Punjabi, that address the following scenarios: ICE worksite raids (for employers), ICE home visits, and ICE public stops.

That’s possible, but the original reasoning was to thwart counterfeiters. Using a black and white printer to print fake money is already going to be a problem.
