What happens when loathing for immigrants reflexively trumps all other concerns?

We learned one answer to this question late last month, when a crucial witness to the Hard Rock Hotel collapse in New Orleans was deported to his native Honduras. The witness, Delmer Joel Ramirez Palma, had reported job site dangers to his supervisors before the collapse, which killed three people and injured dozens. Afterward, he spoke to media and to the whistleblower division of the Occupational Safety and Health Administration (OSHA), which is investigating the incident along with the New Orleans Police Department.
