"50% of problem gamblers abuse their children."
This is pretty much very impossible to quantify and suggests all of the stats this troll posted are made up. Who would be considered a problem gambler, and how would you gain access to whether they hit their kids or not? It wouldn't shock me if degenerate gamblers were more likely to hit their kids though. OK, enough about the troll.
Interestingly my posting reminds me of the made up stat that the day after the superbowl was when the most cases of domestic abuse occurred which I think is a myth, I dunno I'll try and google it.
