Why do parents refuse to discipline there kids?

Do they not understand the crime that goes on in the country is partly because of no discipline when they were growing up. If your kids misbehave then the should be disciplined. I was ed as a kid and i have to stand in the corner, my parnets yelled at me and i am just fine. That is fine if you do not want to but at least descipline them. Don't leave up to the cops to arest them when they fu*k up before they learn.Let try to make this world a better place and teach our kids right from worng. Give them discilpline and rules they have to follow.
