Interesting post from NYC GOP blogger:

"I got this email forwarded to me on Tuesday (10/4/05) from a coworker. I sent it on to Snopes and some other NYC Bloggers as a potential hoax. Look who's not laughing now.
I do not send out mass emails as games or jokes so PLEASE take this seriously. As some of you know my father works for HomelandSecurity, at a very high position and receives security briefings on a daily basis. I received a call from him Monday Oct 3, 2005 and it was a brief call and did not contain a lot of details. The only information that I can pass on is that everyone should at all costs not ride the subway for the next 2 weeks in the major areas of NYC, that means Grand Central, Times Square, Herald Square, Union Square areas. I know that seems crazy but do take his advice if at all possible. I am not at will or able to discuss anything more than that. I was not allowed to ask him any questions but he called with grave concern for the safety of myself and Heather. He said I could tell friends exactly what I have said above and that is it.
I am sorry that I cannot give any more details. He also said that he would inform me as soon as the threat at hand has passed and when we can go back to normal life.
Best wishes,

Interesting. So DHS guy privately tells his family to stay away from those areas, while everyone else is told to go about their business as usual.
