looks like something cowboy would want to do...
I was thinking the same thing - most of the little boys I know would think that looked like great fun, and beg their parents to do it. This could be a game that they play at home, and she made the poor judgment call to do it in public instead of properly disciplining him. The tape just does not give us enough information.
Let me be clear -I'm not saying it's right, or smart, or not dangerous, I'm not saying she's a good mom who is misunderstood, all I am saying is that we do not have enough information from this video to make a snap judgment. Her parenting ability definitely need to be investigated.
