I ran across this story on dailynews.com earlier.

In an effort to balance the rights of convicted sex offenders with the need to protect children from harm, a City Council committee today approved a proposal to urge landlords and tenants to report suspicious behavior, using the non-emergency 311 line.
The Public Safety Committee's plan came about after city lawyers said it would be unlawful to require landlords to check the Megan's Law database, which lists designated registered sex offenders, before renting an apartment to a prospective tenant.
Instead of drafting a new ordinance, committee members endorsed a plan that would allow anyone to dial 311 to report what they consider to be odd or suspicious activities around apartment buildings. Operators will forward complaints to the Los Angeles Police Department.
Information on the program will be posted on the city's Web site and television station, Channel 35. Should funding become available, city officials also plan to print a poster that landlords could place around apartment buildings to advertise the program.
"What we are doing here is something that everybody is thoroughly excited about because it is a partnership between our associations and landlords and government to solve a problem that, to say the least, is a huge problem," said Tara Bannister with the California Apartment Association. "I have personally been involved in hundreds of (cases with) landlords who have had to pay off sex offenders to move out to protect the other tenants. This will solve that problem."

It definitely reminded me of the Rodriguez case. Definitely a thorny issue.... I'm working on another one looking at the issue, so stay tuned.
