Just a walk around the neighborhood reveals their presence. At the Rock Island stations, in the coffee shops, at the Jewel, CVS, the carwash, at the parks, even at Dunkin Donuts, watching, watching, watching, making list, taking photos, reporting and getting ready. Suddenly, longtime employees at local businesses have been replaced by people that don't talk much but when they do, it is with a strange accent.
Be sure to lock your doors at night and don't ever open them for strangers. Promptly report all suspicious activity to the 19th Ward Office.
