Recidivist transit grinder

See Gothamist post, "Recidivist Transit Grinder" Blames Big Apple Babes. It's interesting to see the public and media react to a crime that's considered fairly common from our perspective in the office.

My only critical comment is about the label "recidivist transit grinder," attributed to ADA Contillo. In the office, we normally call them 'subway grinders'. I wonder why ADA Contillo used, or at least was quoted using, 'transit grinder'?
