For better or worse. But what it means is that if, oh, you're at Andrew on the Red Line and you decide it might make sense to throw some metal object onto the third rail and the T has to stop service so it can retrieve that item, chance are good Transit Police will pull a snap of you of one of the surveillance cameras, which should make it easier for them to find and arrest you.
So if, hypothetically, you know somebody with a light blue hoodie who might have done something like that around, oh, 12:30 a.m. on Tuesday, detectives are standing by at 617-222-1050 or you can text an anonymous tip to 873873.
