There's no argument against leaving little kids alone whilst you go off for a meal, drink whatever.... They have to live with that, I know I couldn't, your role as a parent is to protect your kids, you shouldn't leave them in a situation where you can no longer protect them IMO....hanging them, locking them up etc will not hurt as much as the knowledge you've let your child down and failed the basic Parental role of protection....as on evidence ( not hear say, conspiracies etc) they have not been charged with hurting their child, so are they not right to keep this in the public eye for ever...
