As we consider how to reform immigration, one question is whether or not the U.S. should continue 287(g) programs, which allow local law enforcement officials to act as immigration agents. The article linked here clearly argues against this, with good reason.
Immigration enforcement deserves the full attention of the federal government. It is a federal issue, but more importantly, it's clear that local immigration enforcement leads to corruption and potentially institutional abuse of immigrants on the local level. I also think that many of these laws are thinly veiled attempts to legitimize racism.
