Lawyer Alan Dershowitz has weighed in on the accuracy of FX's American Crime Story: The People v. O.J. Simpson.

Dershowitz, who served as the appellate adviser on the O.J. Simpson case in the '90s, told the New York Daily News this week that The People v. O.J. Simpson is not accurate.

"It's totally inaccurate and Jeffrey Toobin's book (1996's The Run of His Life on which the show is partly based) contains many inaccuracies that were fed to him by Bob Shapiro," he said.

One of Dershowitz's biggest issues with the miniseries is the amount of information that seems to be in violation of attorney-client privilege.

"To me the fundamental question that gets raised by the whole episode is: why there are things in there that are supposed to be covered by lawyer-client privilege," he said. Specifically, Simpson failing the lie detector test as presented in episode 1 appears to be a breach of that privilege.

"How did that get out? Some lawyer clearly violated the lawyer-client privilege to disclose that," he said.

He noted that there are only four people in the world who could have known what happened in that room: Simpson, Robert Kardashian (who died in 2003), Robert Shapiro and the lie detector administrator.

The People v. O.J. Simpson co-showrunners Scott Alexander and Larry Karaszewski have yet to respond to Dershowitz's claims.

American Crime Story: The People v. O.J. Simpson airs Wednesday at 8 p.m. ET/PT on CBS.
