O.J. Simpson may have convinced jurors a decade ago that he didn't kill his ex-wife and friend – but at least one Portland bookseller isn't persuaded to hawk his new tome.

The Looking Glass bookshop downtown says it won't sell, "If I Did It", the new book in which the former NFL star describes how he would have killed his ex-wife, Nicole Brown, and her friend, Ron Goldman – "if" he did it.

"I'm not going to support that kind of publication," says Looking Glass owner Karen Anna. "It's a re-creation of a really terrible incident. Whatever the motives of the publisher, it's unconscionable."

That decision differs from that taken by major national bookshops like Borders and Barnes & Noble, which will sell Simpson's book. So will locally-owned independent seller Powell's.

"We haven't ordered it in very large quantities, but we are selling

it," says Powell's spokesman Michal Drannan.

"If I Did It" will be published by Judith Regan, who's produced other headline-grabbing books such as Jose Canseco's "Juiced." "If I Did It" is due out Nov. 30.
