Also, on Lies point, in Aus most 'gang tags' are more prone to be a bunch of muddle headed binge drinking dickheads who are quite likely still of school age, not the local cocaine distribution network. So there's some cultural differences there.
Like, the Bra Boys will bash people sure, but it's not even close to messing with say, Bloods or Crips. So far as I'm aware.
Also, 000, do you have a link? I'm familiar with the experiment but would love to see it again. As far as I remember it wasn't so much 'moral judgement is affected' as much as 'when people see rules being broken, they are more likely to break other rules'. I accept the general finding though. IIRC, along with graffiti, the put bikes on a 'no bikes' section, and found more people ignored a 'stay off the grass' sign.
I'd have to look it up ... It was done by the University of Groningen, even.
One (not quite) surprising result of the experiment was that they put a mailbox in the alley, with a letter hanging just half out the opening. The envelope had one of those plastic "windows" in it, through which one could clearly see a 20 euro note. In the graffiti'd version of the alley, significantly more people pocketed the envelope, instead of (the morally right action) pushing it back in, so it would fall through the opening. It's a really nice moral test, IMO, because once you pushed it in, you can't get it back, so you only need one moment of "moral clarity" to do it, and afterwards you no longer have a nagging feeling like "someone else will take it" or a banknote staring at you.
