Patterico offers his Los Angeles Times Year in Review post. Here's some more bias from that paper specifically relating to immigration matters:

Dec: Danced around the status of a cop shooter. Backs Bill Richardson's opposition to border fence. Elizabeth Mehren said that Mitt Romney directly employed illegal aliens, when they were actually employees of a lawn care company with which he'd contracted.

Nov: Lionized and continued to cover up for Los Angeles Mayor Antonio Villaraigosa. Editorial engaged in the Graf/Hayworth canard.

Oct: Peter Wallsten: the GOP can't win without opening the borders. David Streitfeld/Los Angeles Times promotes illegal immigration. "Food Stamps in Four Hours" (Mexican consul+USDA)

Sep: Los Angeles Times reporter Sonia Nazario promotes illegal immigration on CBS News. Reporter Lee Romney promotes "guest" worker schemes. At an immigration march, they gave in to union thuggery. Joe Mathews didn't ask about the immigration status of hotel workers engaging in political theater. Patt Morrison opposes the border fence.

Aug: Jordan Rau falsely claims that "liberals and Latinos" "strongly" support driver's licenses for illegal aliens. The numbers aren't there.

Jul: To their credit, they issue a partial indictment of what they support. A few days before: Molly Hennessy-Fiske/LAT promotes corruption in Arkansas. A few days before came the slightly more balanced "Vision That Inspires Some and Scares Others: Aztlan".

Jun: Alicia Robinson of Orange County's Los Angeles Times-affiliated Daily Pilot promotes Mexico's "IDs for Illegals" identity card.

May: Los Angeles Times supports Bush immigration speech (editorial).

Apr: Columnist Steve Lopez thought massive immigration would help a low-wage legal immigrant. They join those who refer to foreign citizens marching in our streets as an "Immigrant" Rights Movement. They conduct a puffball interview on immigration with Antonio Villaraigosa. Partially on the other hand, they disclosed Bush's Aztlan video. Tim Rutten slams Lou Dobbs. Put a smiley face on students marching for illegal immigration. Anna Gorman misleads on workplace enforcement.

Mar: Printed a pro-illegal immigration ad from the Mexican government. Reports on massive trash dumps left behind by illegal aliens... and blames it on the Border Patrol. OTOH, they give a couple paragraphs to the downsides of Maywood's support for illegal immigration.

Feb: Christopher Goffard discusses the illegal aliens who "oil the gears of [Orange County's] humming economy"

Jan: Peter Wallsten plays the 187 canard among many other misleading statements.

I didn't cover the L.A. Times' coverage of the illegal immigration protests, but I'd imagine it was in line with the above.
