That is the new and excellent Sam Quinones article from Pacific Standard, here is one excerpt:
Some of this is a state and national story, as violent crime declined by about 16 percent in both California and the nation from 2008 through 2012. But the decline has been steeper in many gang-plagued cities: 26 percent in Oxnard, 28 percent in Riverside, 30 percent in Compton, 30 percent in Pasadena, 30 percent in Montebello, 50 percent in Bell Gardens, 50 percent in El Monte.
Santa Ana once counted 70-plus homicides a year, many of them gang-related. That’s down to 15 so far in 2014, even as Santa Ana remains one of the densest, youngest, and poorest big cities in California. “Before, they were into turf,” says Detective Jeff Launi, a longtime Santa Ana Police gang investigator. “They’re still doing it, but now they’re more interested in making money.”
No place feels so changed as the city of Los Angeles. In 2014, the Los Angeles Police Department announced that gang crime had dropped by nearly half since 2008.
Obviously this is welcome news, not only for its own sake, but also for those of us who have been arguing that Latino immigration is going to work out.
