Chip: I was still in LA when the homeless population exploded following the passage of Proposition 47. Prop 47 redefined a lot of felonies into misdemeanors, and allowed prisoners to petition for release. The petition process included no right by the prosecutor to have the criminal evaluated for mental competence or safety. The proposition resulted in tens of thousands of prisoners - many (most?) with drug addiction and mental illness - to be poured onto California streets.
The homeless prison population - unskilled, drug-dependent, many with mental illnesses - started taking over large portions of downtown Los Angeles in early 2015. A main north/south thoroughfare called Beaudry Ave. is now home to dozens, perhaps hundreds, of homeless living in tents and cardboard boxes covered with plastic tarps. Skid Row, the area around 3rd St. to the south and 7th St. to the north, bordered east/west by Main on the east and Alameda on the west, is simply inundated with the homeless, by the thousands. The stories of what the criminal, drug-addled, mentally-challenged homeless have done to the area are numerous. I have posted some in the past couple of years.
So the San Fernando Valley, San Gabriel Valley (to the northwest and north), Glendale, Burbank, and South Bay (Redondo Beach, Manhattan Beach, Torrance, Westchester, El Segundo) remain attractive communities with single-family residences, well-kept lawns, and good public parks. History shows, however, that eventually, the city will move the homeless to these areas to try and alleviate the problem.
Los Angeles County is hell-bent on self-destruction. The very poor, untrained, unskilled are increasing dramatically as a percentage of the population. The tax base is moving away. We need but look at the inspiring models of Detroit, Newark, and Baltimore to see where this winds up.
But no worries. The entrepid mayor, Eric Garcetti, is full-steam ahead on ... fixing global warming. So I'm sure he has brilliant plans on getting criminals with drug problems and mental illness off the streets.
