Oh, believe me. Even with the mask on, the modern technology can be used to identify the thugs. It is harder, I agree, but nonetheless, very possible and doable. The question is whether the detectives would want to to go an extra mile to investigate or just drop it. With all due respect, there's been so much shit happening in Queens these days, I bet the Police is overwhelmed with reports. Unless it is serious, chances are it will go unsolved. Thugs are targeting "vulnerable" business these days. Be safe out there.
