Driver parked and blocked 3/4 of a private driveway during rodeo celebration where all cars were parked on the street thus blocking any entrance and exit of personal vehicles from the driveway. Noticed open container of beer in driver's cup holder.
When these people were approached about their vehicle, the woman who was a passenger got extremely angry and hurled beer, spit in my face, and threatened someone else with a knife and stated she didn't care if we couldn't get out of our driveway when we told her the owner was diabetic and may have an emergency. Plus emergency medical people were also blocked in. They also had two children in the back of the car.
