One of our local agencies, A, has a well-deserved reputation for zealous DUI enforcement, especially when it comes to officers from a neighboring city, B. One officer in particular from agency B has been arrested twice by agency A, only to have the charges dismissed because his BAC was at a .02 or .03 both times. Most officers from agency B avoid driving through city A if they've had anything to drink at all, but one apparently missed the memo and drunkenly crashed his POV into the fountain that is in front of city A's municipal complex (city hall, police headquarters, courts, etc.) He fled the scene on foot, but considering his car was registered to him and his agency B-issued duty weapon was in the car, it didn't take long to track him down.
I worked a case where a drunk guy followed someone into the secure parking lot of the Tucson Sector Border Patrol station. When initially contacted he said he was driving his friend home, then gestured to the empty seat next to him. He kept saying variations of "fuck you, baby" to the female Tucson PD Officer called to the scene, and at one point "attempted suicide" by holding his breath. Somewhere during the course of the investigation, he ended up at a hospital for some sort of "treatment." The medical staff determined that a catheter was necessary, and administered such. As a prosecutor with no medical training, I felt it wasn't my place to second-guess their expert judgment.
At some point I need to look through my stuff to see if I still have the picture, but a drunk guy on probation for his last DUI, while driving his friend's lifted Chevy truck, managed to drive due east on a north/south road. This short journey came to an end when he jumped the curb, drove up a 4-5 foot high dirt berm that was perfectly shaped as a ramp, and dropped the front tire directly through the windshield of a parked car, without touching the front bumper or hood. He then took off on foot, dropping his open bottle of liquor as he went. When we interviewed him (making sure to get pictures of his Crown Royal hat), the thing he was most upset about was that one Officer, after asking him why he didn't go back for the bottle after he dropped it, informed him that, in addition to DUI, he was also going to be charged with alcohol abuse.
