I found myself wondering how the nation’s 10 highest-grossing firms are responding to the tragedy in the Gulf. Using The AmLaw 100 list, I visited the Web sites of the top 10 firms. I found only one that had a reference of any kind to Katrina — an offer by Jones Day to help businesses recover insurance proceeds. Obviously, the silence of a firm’s Web site does not mean the firm is failing to act; I did not call each firm to ask about this. But I hope that large firms are using their resources to help in this time of national crisis.
