Tom Henderson Don't send any text messages or e-mails you don't want to see in the newspaper was a lesson Detroit Mayor Kwame Kilpatrick learned this week, and one repeated by area attorneys and business consultants. "I advise everyone and practice it absolutely. I don't send anything I don't want public," said Mark Malven, leader of the technology transaction practice in the Bloomfield Hills office of Dykema Gossett P.L.L.C. "I don't put anything sensitive into an e-mail or a text message that I wouldn't want to see in the newspaper. Executives have come crashing to the ground. Companies get ruined." ... Cendrowski said he advises clients to be particularly careful not to text message or use wireless e-mail to discuss such things as business intelligence or trade secrets. Savvy snoops with the right equipment within broadcast range can easily capture those messages.
