Is Crime down on the 7 train?

Ever since iPhone (and other un-cool smart phone) theft has gone up on the subways in NYC, the NYPD has deployed undercover agents on the trains throughout Manhattan. However the 7 train (and others in the Bronx) have police officers in full uniform instead. Conductors have been announcing the presence of these officers and in return, crime on the 7 train has gone down (to pretty much none!).

Do you feel safe on the 7 train?
