People think of lawyers as professionals who are paid to parse the English language until the alphabet bleeds. But James Best of Best & Associates, a four-lawyer firm whose specialty is suing for damages after car accidents, is uncommonly unslippery about the kind of services he offers. To wit: He placed a fiberglass cast of a great white shark atop his offices on Central Expressway. When reached for comment about his courtroom style, Dallas' own Clarence Darrow replied: "If people want to hire a nice lawyer, they [can] ask their grandma. People want a mean, aggressive lawyer, not some pussy." Huh. You don't say.
