Good thought. Yom Kippur is Tuesday sundown-Wednesday sundown. I live in Manhattan and will be taking taxis to and from work for the remainder of this week and next week.
Smart move, to take taxis or surface transit...but we can't forget that the London bombers also hit a bus.
I have nieces and nephews in NYC that take the subway every day. I hope they will make other plans until these Manhattan area cells are broken up and all the culprits arrested.
The info has been known by Bloomberg and the Police Chief since Monday. That's another point that seems to connect the NY threat with the OK failure.
