An interesting development I have seen this year is the increased reporting of local police crackdowns on sex offenders on Halloween. From Newsday:
In Suffolk, Probation Director John Desmond said sex offenders are required to go home directly after work and are not to be out publicly until late evening. The county currently has 825 registered sex offenders. Ohio, Tennessee, Maryland and North Carolina have adopted similar restrictions.
The article does note that the Suffolk program is three-years old. I'd be curious to find out how many of these programs are new this year.
