Larry Bortstein has a stock answer for people who ask him about the dramatic demise of Lehman Brothers. “The expression I use is that it all would have been very interesting if it were happening to somebody else,” says Bortstein, name partner at New York’s Bortstein Legal Group.

At the time of the financial services giant’s collapse, Bortstein wasn’t just one of Lehman’s most senior in-house attorneys. He was also global head of its technology law group, and thus knew as much as anyone about key vendor contracts and about how the firm’s vast technology infrastructure generally worked.
