It's a challenging period. It's clear that our transit system is a ripe target [for terrorism], if we have learned anything from London and Madrid. The good thing is that these suspicious packages are spotted and found. The increased NYPD presence definitely helps. However, the MTA leaves a lot to be desired. They are slow to recognize the need to harden the system against potential attacks.  -   John Liu     Quotes
