NYPD is back to a standard 8 Hour 35 Minute Tours, with the exception of anyone that gets notified/volunteers for the WTC Security Detail. That is still a 12 Hour (actually 13-14 Hour Tour by the time relief shows up!) tour.
The National Guard and New York State Troopers man the battery of check points. I still would like to see the Guardsmen with fully loaded M16's though, instead of totally unarmed.
Security in NYC is extremely tight and people in Patrol Burough Manhattan South seem to be very paranoid now that the anthrax scare is in full effect. I get multiple calls a night for suspicious white powder found in an alley or back street somewhere. Usually a 10-90X (police radio jargon...basically a bullshit call)
Also we have to respond to a multitude of bogus bomb threats that have to be taken seriously...WTF? You'd think given the fact that 5000+ people, NEW YORKERS!, have died in less than an hour people wouldn't fuck around and call in phoney threats. I had one guy call the staion house with a passable Arab accent saying he was going to blow up my precinct station house. After I hung up on him he called back over and over, so I told him to come down and do it, I would also personally meet him at the front door and show him a fine ass stomping. Looks like that worked, the "terrorist" never showed up.
"Ground Zero" is a cleanup project now. All building/airplane parts are sifted through at Staten Island. You can still smell the WTC burning every night in the air.
The other NYPD cops on this board should be able to hook you up with more info. This is just my perspective.
