Again, you have to realize the 'reality vrs what we say' aspect of JW-hood. Of course Mr "We're so squeaky clean you can eat off of us" JR Brown, Press Officer extraordinaire can trot out lot's of WT and other articles that seem to prove that JWs don't 'encourage' physical punishment. Of course, and JT puts it "Which way is the SOCIETY leaning?" All good JWs can read between the lines, not too mention the good old environment issue, as many JW children are the product of several generations of JW and the parents were raised by the belt, so too the new generation will be raised by the belt.
Not too mention all the 'well meaning' sisters that preassure new parents into 'punishing' children for being children and doing things like playing at the meeting (o horrors of horrors, how dare they do THAT!). Or better yet the 'ones taking the lead' - read elders - telling the parents to get their kids under control and stop being a 'distraction'.
The funny thing is that it's only a distraction since the freaking meeting is so damn boring that people would rather do ANYTHING than listen to the talk ...
