Major League Baseball formed an investigative unit to combat drug use:

"The department of investigations will have critically important responsibilities in protecting the integrity of our sport," commissioner Bud Selig said.

Dan Mullin, a former New York City Police Officer who had been in baseball's senior director of security operations, was appointed vice president and head of the unit. George Hanna, a former FBI employee currently in baseball's security department, was appointed senior director of investigations.

MLB said the unit "will have broad authority to conduct investigations." The limits of the unit were not immediately clear. Will it place moles in clubhouses? Will it secretly tail players away from ballparks?

I'm actually a bit surprised a unit like this didn't already exist. I hope it doesn't turn out like this.
