WHY ICE MEMBERS WEAR MASKS

AS A PART TIME INVESTIGATED JOURNALIST, SEEKING OUT THE TRUTH IS A FULL TIME JOB. FOLLOWING THE ICE DEPORTATION RAIDS, I WAS ALWAYS PUZZLED WHY THEY WEAR MASKS TO COVER THEIR FACES. WHO WOULD HAVE GUESSED THAT THOSE OLD X-RAY VISION GLASSES THAT I ORDERED OUT OF THE BACK OF A COMIC BOOK FOR 25 CENTS, WOULD HELP ME SOLVE THIS MYSTERY.
