How can anyone oppose this? It protects the migrants as well. If one goes missing we can help identify them that way. Lots of gangs, sex trafficking and drug trafficking so why wouldn't we? If they got separated from family we could identify then this way too. And on the other side of the argument, we have a data base of prints that can later be used to, if needed, to identify suspects. If they have no intention of commuting a crime then why is it a problem? Americans require fingerprints for many things. Why would we exclude immigrants? So why in the world wouldn't we support this!? It literally only benefits criminals not to do this!
