'Power Grab' in Vegas Over Jackson Case

A turf war between Las Vegas law enforcement on one hand and the DEA and the LAPD on the other could have compromised yesterday's raids on Dr. Conrad Murray's office and home ... according to multiple law enforcement sources.

We're told the DEA and LAPD wanted to conduct simultaneous raids in Houston and Las Vegas to maintain the element of surprise ... but the Vegas raids were delayed 6 days.

Sources say the D.A. in Vegas threw up road blocks and delayed for days before going to court to obtain a search warrant ... A member of the D.A.'s office told us it's routine for prosecutors to be "careful" in securing warrants.

But sources in other agencies involved in the searches scoff at the D.A.'s concerns, claiming this was nothing more than the D.A. wanting to call the shots.

And several sources say the Vegas police slowed things down by trying to take the lead over the DEA in executing the warrants.

One top law enforcement official says, "There was more than enough probable cause to get a warrant." Another law enforcement officer called the actions of the D.A. and police "a power grab."

The Vegas raids were conducted yesterday ... 6 days after the Houston raid. That gave Dr. Murray more than enough notice that the other shoe was about to drop.

The Las Vegas D.A. would not comment. As for the Vegas PD, a spokesman told us "We're not aware of any feud over the action involving this warrant."
