Security expert Bruce Schneier gives several reasons why undocumented workers should be allowed to get drivers licenses. Among the reasons, 1) state driver’s license databases contain much data on a person including photos and thus can aid law enforcement, 2) a state DMV does not have the resources to validate citizenship quickly and accurately, 3) if denied licenses, the undocumented will simply get fake ones, 4) if will not stop terrorism because any government-issued ID can be used to board a plane.
We are all safer if everyone in society trusts and respects law enforcement. A society where illegal immigrants are afraid to talk to police because of fear of deportation is a society where fewer people come forward to report crimes, aid police investigations, and testify as witnesses.
