Everyone wants something for nothing these days.
The stealing of that kit isn't the only way it happens.
At a show once, I saw a guy (thankfully got disqualified) trying to bribe a judge for a vote in his favour. Also saw a guy get caught trying to remove another modeler's name from the information card about the model and put his own name on it so he could take credit for it.
I've also seen that typical garage and yard sale tactic of stacking one item on top of another to hide it so their paying for one and walking away with two.
Not only do the perpetrators seem to have more rights than the victim, I can only see it getting worse because (in North America anyway) its getting almost impossible for parents to properly discipline their children without some politically correct, child empowering zealot jumping at them for "child abuse"
I don't like to see child abuse anymore than the next person, but I got my fair share of swats on the rear end when I was little, right from wrong was a pretty easy concept to follow after a few of those.
Good public conduct starts in youth and the line between disciline and abuse isn't as fine as some would have you believe.
Sorry if that strays a bit off topic, we can't do anything about the upbringing of the thief of that kit and the life lessons that he or she encountered growing up (that is of course assuming they are grown up) I don't have kids and I'm not sure I want them if the current trends of constricting what a parent can do to make certain their kids can be decent, respectable and respecting citizens keep up.
Sorry again for ranting off on a tangent, but I've got some dire concerns for the directions societies seem to be moving in, the subject of this thread is just one of many societal symptoms that fuel my concerns.
