Public media

Media and children nowadays
one of the good memories of my early youth has been the outdoor play i uses to do with my big brother and our neighbouring friends-from hide and seek to marble games, slap match, tips, you name it and we did it. Playground was fullllll of chn we frequently met new kiddos around the town hah
With today's exposure to child crime-kidnap, pedophile, rape, spam, stalk etc etc as well as violent setting of war, csi, heroic fight and all that in the public media, it seems as though more parents (than those in my childhood) like to keep their kids in the safe zone of 'Play where i can see you' (Helicopter parenting?)
 Of course on top of this there is the law highlighting the responsibility of a guardian to be with the chn all the time as well as game and technology advancement getting them to stay inside more and more. Really? Yet the government is worried of children not exercising enough and having high obesity rate? I dont wanna sound political but to  me it seems like as though there  is not much childlike childhood available to children. Maybe Some may say That new generation have different way of enjoying their childhood but here I leave with a question, why on earth then, are there more worries of today'S children from all than before while all these violence of child crime and war actually did exist from long time?
