I disagree. I think the better analogy woudl be: "I saw an unlocked vehicle today and I think its important that all vehicles remain locked. Since they didn't come running out when I told them to lock the car, I [opened] the car and left a note on the dashboard stating I'd been in the car."
"And then I went into the bad part of town and distributed fliers all around about how the car at the corner of Main and Screwed had been left unlocked for a while and how it had a great stereo and iPod in it."
Still a bit off. "[going] into the bad part of town" would imply he went on some devious message board and there released the information with a flashy heading.
"And then I went into the bad part of town and distributed fliers all around about how the car at the corner of Main and Screwed had been left unlocked for a while and how it had a great stereo and iPod in it."
