If they're doing the sh gig for real, they're going to get themselves seriously hurt, possibly killed, lot of guns over there right? More guns than bulletproof superpowers I imagine.
If they are not serious, then they are just kids playing dress up, who haven't got a clue what they're talking about or messing with.
edit: First thing a crook is going to do to that mask is pull it over his eyes, that has to be one of the dumbest things you can do, put risk to your eyesight. These guys don't know what they are doing.
If you want to fight crime and disguise yourself, just wear a fake moustache, prosthetic chin, crap like that, or better still get one of those life like rubber masks and only wear it on the bottom half of your face, nowhere near your eyes.
Also, going on the news? Along with the stupid mask, this suggests they are just attention seekers, as Rorschach said in the movie WM, 'I'm not in it for the ink.'
The best way to be effective way is for folk not to know you are out there.
