NEW YORK (AP) -- The family attorney of Michael Jackson says an involuntary manslaughter charge against the pop singer's personal physician would be insufficient.

Brian Oxman calls the charge, with its maximum jail sentence of four years, "just a slap on the wrist."

Jackson's death on June 25 came after Dr. Conrad Murray administered the powerful anesthetic propofol and two other sedatives, according to the Los Angeles County coroner's office, which ruled the death a homicide.

Murray is ready to surrender to authorities if prosecutors file charges, according to his attorney, Ed Chernoff.

Murray says nothing he gave the singer should have killed him.

But Jackson attorney Oxman tells CBS' "The Early Show" on Wednesday that Murray displayed recklessness in dispensing the drugs, warranting a second-degree murder charge.
