The problem with "US" is we do need to be kept an eye on.
Some think it is normal to be taking recreational illegal drugs in the name of the contstitution.
Others might think it's OK to kill the neighbor's pets and to BBQ them for dinner.
I'm sorry to say there are some wierdos among us, plus many are not blessed with the gift of common sense.
So, for those lacking, lots of laws exist.
In the case of kids, they are protected over the parents if they are shown to be in danger by the parents.
If a guardian is home getting drunk while kids are in the house and children's services finds out, you are going to lose the kids unless there is a sober parent there the same time to protect the kids.
There is a balance and I think what we all want is to not have the balance turn into the government dictating to us how to live in general, which is reasonable.
Uh, yeah, I'd say some of US do need to be kept an eye on.
