Multiple blocks would be skid row in downtown under LAPD's watch and nowhere near the radio location given for the murder near the airport. Smaller tent cities are dotted all over the Southland. Some city police departments are better at pushing them away than others. There is a rather infamous photo of one freeway overpass along Venice Blvd. on the Los Angeles side of the street it is tent city, across the city limits line on the Culver City side of the street, with their independent police department , clear as glass.
At the moment going into the real life Super Tuesday election it seems to be the primary issue on the mailed political ads for L.A. County Supervisor. One candidate being a termed out LA.. City Councilman saying he has the experience to deal with this problem while his opponent who is lucky enough to be coming from a different political office so can't have the tent cities blamed on her is saying that the Councilman is the cause. When being a one party state they all have basically the same political policies.
