Did they do that? Or did they throw out the ones with valid visas too? (hint: It was the latter. Details are in the article.)

The bigger problem is that they "invalidate" your visa post-facto, on a whim, for whatever they want. Attend a political protest? Have a 20 year old bad check on your record despite having lived here for 50 years, since you were a young child? Embarrass a politician? I've seen all of those and more result in a legal immigrant having their visas cancelled and then thrown in jail until they can be deported.
