Today in subway atmosphere news, we learn from WNYC that the NYPD is partnering with Brookhaven National Laboratory to study how chemical weapons might disperse through the city’s underground tunnels. The researchers plan to release a “non-toxic, odorless gas that mimics how chemical, biological and radiological weapons would disperse” in twenty-one subway stations across the five boroughs in July, with 200 sampling devices deployed to monitor its spread.
“We want to be able to determine how toxic material can flow through the transit system, it’s one of the concerns that we’ve had for a while and how it flows on the streets of our city,” Police Commissioner Ray Kelly said in a statement.

A random, longwinded observation of my own. Those “secure beneath the watchful eyes” ads that everyone from Boing Boing down took exception to (years after they were actually on the streets)? I was never that bothered by them, either. At least if you’re going to have CCTV, tell people about it.
