If you want to change c*nts' behavior, don't just take pictures; take ACTION!
I was once driving with a friend of mine, circling a shopping center parking lot a few days before Christmas looking for a place to park, and there were absolutely NO spaces to be had, and then I spotted a little front-engine, front-wheel drive car parked with its ass-end blocking another space. I stopped the car and told my friend to get out and help me. We grabbed underneath the rear bumper of the offending car and were able to lift and move the rear end of the car, inch-by-inch, until the other space was free. Granted, it was a small car, and my friend and I were strong young 17-year-olds at the time, and this was 35 years ago (Jeez, I'm old) when cars weighed considerably less (not as much safety or fuel emissions crap on them). It took a couple dozen "lift and move" operations to get it there. I then parked in the free space, but I never did wait around to see the c*nt's reaction to his car being moved.
Another guy I know told me a guy in a Porsche "stole" a parking spot from him as he was signaling to take it, and the guy just laughted at my friend as he walked away. Well, my passive-aggressive friend had a valve-stem removal tool with him at the time, and he took action.
He removed all 4 valve stems and threw them as far away as he could, and then replaced the caps to hide the fact that the valves were gone.
Although my friend told me that he didn't wait around to see what happened, he imagined this scenario: C*nt comes back to his Porsche and sees all 4 tires flat, and calls a tow truck. Tow truck arrives to put air in tires, but no valves, so if tow truck driver doesn't carry spare valves, he has to make another trip to get them. C*nt had to spend time and money for being a c*nt, and couldn't recoup any money from insurance company because there was NO DAMAGE!
The lesson here:
"Don't be a c*nt"
Life! Life, do you hear me?! Give my creation LI-I-IFE!
