As another illegal immigrant defied a deportation order and sequestered himself in a church in New Haven the other day, Mayor Toni Harp welcomed him and proclaimed: “New Haven will remain a sanctuary city. We are not going to engage in helping to report our law-abiding citizens.”

But, of course, by definition illegal immigrants are not law-abiding, and the latest one seeking sanctuary in New Haven, like the last one, received a deportation order years ago and then some temporary stays before he was denied another. While he seems harmless enough, terrorists and other ne’er-do-wells might be cheered by the mayor’s assurance that anyone who breaks into the country illegally and makes his way to New Haven should be exempt from law enforcement because New Haven substitutes its own immigration policy for that of the United States. No foreigners need to be vetted before arriving in New Haven.
