The students learned a practical lesson as well from last week’s protests. In Los Angeles, you can do just about anything – dress any way you like, act as crazy as you wish – as long as you don’t mess up traffic. It seemed the ire of local officials and the public toward the demonstrators escalated as the students took to the freeways to interrupt traffic. State Treasurer Phil Angelides has been on the campaign trail so long that he seems to be finding it difficult to separate when he is shilling for himself or a product. Angelides was appearing last week with talk radio’s Ron Owen in San Francisco when the host began reading a spot for a mattress ad. Playing along, Angelides extolled the virtues of a good mattress when the host mentioned the sponsor’s name. “Did I just participate in a product placement?” Angelides asked. Replied Owen: “What do you mean just? We’re doing it right now.” Staff Writer Harrison Sheppard contributed to this report.

After the mayor praised the students for their efforts on behalf of illegal immigrants, he then chastised them. The students, who wanted to hear “si, se puede” not “go back to class,” told an abashed Villaraigosa – in strong Spanish street slang – what they thought of his ideas. The following day, Villaraigosa took an even sterner approach, authorizing the Los Angeles Police Department to step up its action against truant students. The mayor’s difficulties with the students provoked both anguish and a bit of concealed joy among school officials. Anguish, because officials were hoping the mayor could appeal to the young people to return to class. But they couldn’t help but smirk a little as the mayor – who has made much of wanting to take over the school district – learned what every parent could have told him about the difficulty in getting through to a stubborn teen. When actor-comedian George Lopez got his star on the Hollywood Walk of Fame last week, people were still thinking about the immigrants-rights protests that drew 500,000 people to downtown Los Angeles the previous Saturday. Attending the Hollywood Boulevard event for Lopez, City Council President Eric Garcetti took note of the record-breaking gathering. “Thanks for having me here,” Garcetti told the actor. “And I particularly enjoyed the Lopez family reunion. I didn’t realize your family was so big and so well-behaved.” Every politician eventually learns this lesson, no matter how popular he is: Your friends and supporters will cause the biggest headaches.
