I believe this came up due to how Florida restricts where convicted people can live.

Overview of the Bill

If you are a registered sex offender in Florida, the bill will make it a first-degree misdemeanor to loiter or hang around within 300 feet of any locations where children frequently gather. It will also be a misdemeanor crime for any sexual predators who committed illegal sexual assault against children to approach in public parks or visit childcare or school facilities without notifying the staff beforehand. Taking it one step further, this new law additionally restricts sex offenders from dressing up for certain entertainment activities without prior approval, like posing as Santa Clause or a clown, which draws the attention of children.
