According to the cops way of thinking, black guys only get Lamborghinis by rapping, pro-sports or illegal activities, and sometimes a little of each. So, they take the chance that they'll turn up some "evidence," like a wad of cash, some weed, a gun, etc. When they really want the car, they can just drop their pocket dope into the car, or that spare revolver with the serial number filed off, and viola, a seized Lambo for the department! If I were a rich black guy, I'd buy a freaking Corolla to drive and just live in the most lavish home I could afford. The ride is simply not worth all the negative attention, and I'd rather pull my cheap import into the garage of an awesome house than drive a Turbo Cayenne on dubs if it means getting the shakedown from the man every time I want to take my girlfriend to the salon.
Phoenix police suck ass, but South Tucson cops are worse. Their city is a single square mile in the poorest, most gang-infested part of town, and because of their tiny jurisdiction, they feel inferior to TPD, so they take it out on anyone unlucky enough to get stopped within their city limits. TPD isn't so hot either, but there are so few of them around, you almost never see them in broad daylight, and besides, they're usually doing traffic enforcement to generate revenue. When you do see them, when the city is just crawling with cops, is around the University and 4th Ave all weekend long. The LOVE that DUI money, so they have a huge DUI enforcement unit, including a mobile paddywagon with a breathalyzer, blood draw station and a holding cell which is backed up by at least 4 separate cars marked "DUI Enforcement" which are dedicated (themselves with mobile breath testing machines) to busting people, students, mostly, for walking (for PI), biking (one of my frat brothers was nicknamed "Booey" for getting a BUI after falling off his bike in front of a cop) and driving (or not driving, I knew a girl in college who got a DUI for simply closing the convertible top on her car while waiting outside a bar for a taxi, she had to put the key in the ignition and it was parked on the street, so even though she never started the car, they busted her anyway) after drinking.
There is a substantial difference with the county sheriffs, though. They are actually very, very nice.. for cops. I don't know about Maricopa, I suspect they are as shitty as their boss is (Arpaio) but down here, they are pretty decent. I had a run in with an off duty desk jockey who tried to run me off he road after my friend leaned out of my truck to wave at his girlfriend. This cop thought we had gestured obscenely at her, and was so offended that he chased us home in his pink Ford Taurus, waving his badge at us. We kept driving for a while, but decided it would be even worse if the guy knew where I lived, so we stopped at an intersection off a major street near my house, and the guy jumped out of his car and immediately tried to yank me out of my seat by my shirt, ripping it while yelling and flinging spittle in my face. Some words were exchanged, my passenger reminded the guy he had just committed assault and battery, and after he first threatened to call another officer as if it would intimidate me, I demanded he do it so I could file charges. Since we were just outside the city, a sheriff's deputy showed up. After taking the guy back to his car and giving him a dressing down, she returned to me, apologized, suggested we forget that it ever happened, and assured me she would make sure his superiors knew what he had done (I seriously doubt that actually happened) and she bid us good day without so much as even checking my license, probably so as do avoid any record of the event appearing anywhere official.
I have had a few other encounters with local deputies who were as decent as any LEO could be, in stark contrast to the city cops. Still, the last thing in the world I want is to have any kind of contact with any of them. We have so many around here, Highway Patrol, County Sheriff, TPD, Marana, Oro Valley, South Tucson, U of A, Pima College, Sahuarita, Tohono O'odham, and then there's the Border Patrol, DEA, Customs and ICE all over the place because we're inside the Constitution-free Zone known as the "special border enforcement area." Every little incorporated entity has their own mobile tax collectors shooting radar beams at you, or cooperating with the Feds to look in your trunk for illegals or let the dog sniff around your car. You see them everywhere, all the time, in cars, vans, Hummers, APCs(!), trucks, and on motorcycles, so that sometimes it seems like half the people in this town work for some LE agency. Blech!
