ICE immigration raids sweeping up criminals, plus those who "lack documentation"

A DHS official confirmed that while immigration agents were targeting criminals, given the broader range defined by Trump’s executive order they also were sweeping up non-criminals in the vicinity who were found to be lacking documentation. It was unclear how many of the people detained would have been excluded under Obama’s policy.

Federal immigration officials, as well as activists, said that the majority of those detained were adult men, and that no children were taken into custody.

“Big cities tend to have a lot of illegal immigrants,” said one immigration official who spoke on the condition of anonymity because the official was not authorized to speak publicly due to the sensitive nature of the operation. “They’re going to a target-rich environment.”
