Is this park primarily a playground? Then it may be understandable. Adults really would have no business there except for watching out for their kids.

Or are there walking trails? In that case, they are essentially casting the taxpayers, who I presume paid for the park, as potential hazards, unable to enjoy their own park without being interrogated.

Either way, it's certainly frightening. And what about those adults who are with children? Wouldn't they be just as likely to be pedophiles?

And if a child should fall and her father brushes the dirt off her pants, shouldn't they arrest and interrogate him as a possible abuser?

People have gone way overboard on this issue. It's getting to the point where even smiling at a child can get you into trouble.
