Magic Johnson SWATTED -- But Cops Smelled B.S.

Magic Johnson has just been swatted ... but this one is RADICALLY different from all the others ... because the LAPD is clearly hip to the prank now ... TMZ has learned.

Someone placed the electronic 911 call within the last hour ... claiming multiple shots were fired at Magic's L.A. home. We're also told the caller claimed the shooters were holding someone hostage.

As for the LAPD's response ... it was anemic compared to prior 911 incidents. We're told only a few patrol cars responded. There were no choppers, no SWAT team, no guns-drawn maneuver.

Apparently the LAPD has now figured out the markers that distinguish swatting from the real deal.

Cops on scene quickly confirmed it was a prank.
