It's a curious paradox: Crime rates continue to fall in California, but the number of people killed by the police keeps rising. In Los Angeles County, for example, the number of 2011 homicides was a historic low of 612 people. But the number of fatal police shootings skyrocketed by nearly 70 percent that same year, to 54. That number of fatal shootings by officers was almost equal to 10 percent of the county's homicides last year. Los Angeles is not alone. Nationwide, officer-involved shootings are on the rise, with cities as disparate as Dallas and Albuquerque registering sharp spikes in fatal police shootings. What's going on? It's too soon to know whether 2011 was just an unusual year or the start of a trend. In 2011, 72 officers across the country were killed by perpetrators - a 75 percent increase from 2008. This rough equation makes some sense - if the police are encountering suspects who are more likely to fire on them, they're going to fire back. California is struggling with decades-old budget decisions that have left far too many mentally ill people out on the street, where they can be a danger to themselves and others. Police officers, not caseworkers, are all too often first responders to the mentally unstable. [And] California's ... draconian sentencing laws - followed by prison overcrowding and early release programs - haven't made anyone safer. Legislators and governors have tinkered around the edges of these issues without attempting a full overhaul, but a full overhaul is what the state needs.
