You certainly didn't misapprehend the narrative this article is trying to push. I don't think immigration enforcement should stop as a result of the pandemic, if anything we should be even more determined to discourage illegal entry.
Were the arrests made in any way affected by the state of emergency?
One photo says "David A. Marin, a director of enforcement and removal operations with ICE. ICE officers are being joined by U.S. Customs & Border Protection agents in the last few weeks, as more resources are deployed in sanctuary cities. (Al Seib / Los Angeles Times)".
Was this normal operation, or have the activities against "sanctuary cities" been stepped up; and is that related to State of Emergency powers?
