The NYPD is doing it's best to help night clubs fight terrorism.  To that end they've released a "best practices" document to help guide the way.

It seems like you hear about European night clubs being attacked with alarming regularity so it should come as no surprise that here in America we're being proactive, at least in New York.

The NYPD has released a 27-page booklet called "Best Practices for Nightlife Establishments".  It notably advises owners to be cautious about nervous customers who are sweating profusely and with bulging veins in the neck.  That means everybody on Ecstasy can now be consider a terrorist.

The booklet also says nightclubs should be aware of people casing the establishment by photo or video.  And to be suspicious of patrons with visible wire and tape protruding from their clothing.
