Firstly the McCann case is not a case of child neglect. Secondly, child neglect is a serious problem whether or not someone gets abducted or hurt - the result does not dictate the seriousness of the crime. Thirdly, abduction is the most serious allegation in the McCann case.
Right do you have children?
You do not leave your kids unattended in that manner if you are in anyway a responsible parent, end of story.
To do so shows you either don't value your children enough or you are so bloody naive that you probably shouldn't have kids in the first place.
It was neglect. You do not leave you children unattended to go to bloody dinner with friends. It is highly irresponsible and to be honest I just think you are being contrary for the hell of it now.
