I think its lowlife behavior to mess with somebody's stuff. You might think you are right or just, but they might think they are, too. Let's say they have to send in more machines to retrieve the one you sabotaged, is that better?
Photo and report if it's illegal. Then someone gets an education. Vandalism just creates animosity and anger between groups that each think they are right. Maybe next time that guy goes in, he really tears stuff up because he's seeking some sort of revenge on the do-gooder that left him stranded. Or maybe he has some sort of handicap permit you didn't know existed.
It's almost like using road rage to teach a bad driver a lesson. You get angry and you want them to know that they f-ed up. But you'll never fix that driver. And now you're swimming in the same pool.
