Unfortunately malls are breeding grounds for this type of thing especially ones built with hotels in them. This is where the kids are and they are going to be taken advantage of one way or another.
They will go anywhere where there is any slight chance of people, and preferably children, will be disrobing and vulnerable.
It's terrifying to note that many 'parents' send their children off to the mall for the day and expect it to be their babysitter.
