TODAY IN COURT - MICHAEL JACKSON BODYGUARD TESTIFIES

Alberto Alvarez, a bodyguard who says he was MJ's Director of Logistics, testified Dr. Conrad Murray instructed him to remove bottles from Michael's bedroom -- along with an IV bag with a milky-white substance, before calling 911.

Alvarez says he walked into MJ's bedroom sometime after 12:17 PM and saw Michael laying motionless.  He says Murray told him Michael had "an allergic reaction," then ordered him to collect a bag of bottles and put them in a bag.

And this is big.  Alvarez says Murray then "instructed me to remove the IV bag from the IV stand."

For the record, law enforcement believes the milky-white substance in the bag was Propofol.

Alvarez says there was a second IV bag -- which we know contained saline -- and Murray told him to leave it there.

Alvarez says only after the bottles and bag were collected did Murray tell him to call 911.
