Of course, the article doesn't call out that lie directly. But it notes that they're hired thousands of people, thousands of whom have either quit or been fired. You gotta read between the lines but the article is indirectly acknowledging that people who confront and film ICE are making a difference, as is the chaos from the regime.
There also seems to be a too little too late cleanup operation going on, with ICE firing the walking red flags no normal agency would have hired.
