Business Notes MANAGEMENT

What better way to police a company than to sign up a former top cop? Wall Street's Drexel Burnham Lambert, which agreed last month to settle criminal- fraud charges, plans to hire a new chairman for its holding company. Drexel's choice to succeed Robert Linton: John Shad, the U.S. Ambassador to the Netherlands and former head of the Securities and Exchange Commission. Drexel is also recruiting trade consultant Roderick Hills, another former SEC chief, to serve on the firm's board. Neither had formally accepted by week's end.
