I'd like to say things are demonstrably different here on the West Coast, but I can't (Rafael Perez, anyone?). So how about establishing some standards and maintaining them? Certainly, it would go a long way to prevent needless acts of idiocy by the needlessly hired.
And while you're in full-blown reformer mode, it might be a good idea to eliminate all the artificial springboards and barriers relating to promotions, too. When I suggested putting LASD's "appraisal of promotability" (that portion of the promotional process designed to favor the department's ass-kissers) out to pasture, your predecessor suggested instead that folks like me "get out and network more"—to basically resort to templated leg-humping.
Disgusted, I simply washed my hands of the affair. But lest this sound like a victim impact statement to my career, let me point out there remain in the LASD deputies who are routinely tasked with acting as watch sergeants and watch commanders throughout the county without the stripes or the pay (for all I know, what with the budget cuts, the problem may even be worse now). As these "old reliables" are implicitly deemed trustworthy of assuming positions that tacitly carry the most risk, don't their afterhours performances as the front lines in station operations and risk mitigation deem them more deserving of formal appointment to said ranks? Are they really to be denied promotions because they weren't your predecessor's driver and weren't scratch golfers?
And guess what? Promoting the best and the brightest will have many an ancillary benefit, including a diminished frequency of getting your ass sued. It will enhance the department's image and render it more attractive to desirable applicants. It will avail you a pool of people to draw upon that will constitute a trustworthy inner circle. True, they may not know their roles from the get-go, but you will know yours. It is therefore incumbent upon you to encourage an atmosphere of candor without fear of reprisal among your subordinants. If history proves anything it is that the insulating nature of buffers erodes with time: Sooner or later, you will be held accountable and pleas of convenient ignorance will not appease your detractors. It didn't work for Block or Baca, and it won't work for you.
There are other things that you can do to make the department attractive as possible. How? By re-establishing the "rubber-meets-the-road" brand of law enforcement. For decades you've had one of the best law enforcement media units in the country (doubtlessly an agreeable asset to being geographically situated near the entertainment industry's epicenter). Edify your constituency via podcasts and online videos. Dispense with abstractions like insipid—not to mention hypocritical—mission statements and make compensatory efforts at remediating your constituency of the laws so that next time they clamor "I know my rights" they actually will.
