A quiet moment on Wall St. When I walk by the New York Stock exchange in the morning, it's almost overflowing with people. After the London bombings, security has been heightened even more; this morning I saw cops armed with machine guns. It's practically impossible to get a car near the building, and any car that does has to pass multiple inspection check points, as well as be searched by the canine unit. Do you notice federal hall at the end of the block?
