A Garcetti flight risk: Katharine Macdonald was seated near Dist. Atty. Gil Garcetti on a Southwest Airlines flight when a flight attendant brought him a can of fruit juice.

“In case you haven’t had enough o.j. over the last six months,” the attendant quipped.

Media barking up the wrong tree?The buzz at Camp O.J. was that the prominent role of Kato, the Akita watchdog, in the Simpson murder case had induced Dog World magazine to assign a writer to cover the trial.

“It’s in the works but we’re not completely committed to doing this story,” a spokeswoman told us from Dog World’s headquarters in Chicago.

She declined further comment except to say, “We’re not revealing the identity of this reporter. We don’t want him involved in the media hype.”

We let it drop at that. No use hounding her.

Welcome to L.A.: For 35 school kids from Calabasas, the highlight of the field trip to Downtown L.A. was supposed to be a ride on L.A.’s new Red Line subway. But when the bus from A. E. Wright Middle School pulled up in front of Union Station to unload the kids at the Red Line stop there, a guard intervened.

“You can’t stop here,” he said. “Buses have to follow the arrows.

Of course--the arrows.

Unfortunately, the bus driver followed the wrong arrows and ended up on the El Monte Busway, heading east, in the direction of New York. The kids’ unscheduled field trip took them to Alhambra before they could get turned around, a school aide said. By the time they got back Downtown, there was no time for a subway ride.

And this little piggy went to the slammer: A Pasadena postal employee, unable to reach animal control authorities, phoned police to say that a pot-bellied pig was romping about in the parking lot.

Upon arriving, the gendarmes pondered how to make the arrest. Handcuffs didn’t seem appropriate or functional. The worker pointed out that he had fed the animal some cake, which was quickly gobbled up.

So the cops laid out a trail of crumbs into the back seat of their car. The pig ate his way into custody and posed no further problems despite an apparent sugar high.

“He was sitting on the back seat kind of oinking and snorting,” Police Lt. Alex Uribe said.

The animal was taken to the Pasadena Humane Society, where he turned out to be a she named Tinkie. Her owner later claimed her, spoiled appetite and all.

miscelLAny The Simpson trial is overshadowing L.A.’s longest-running mystery, the death of “La Brea Woman.” Her skull and other bones, recovered from one of the La Brea tar pits and later reconstructed, are on display at the George C. Page Museum on Wilshire Boulevard. Scientists believe she died from a blow to the head. Murder? Accident? It’s hard to say since the incident occurred about 9,000 years ago. And no trial transcripts have been found.
