Before you take the kiddos trick-or-treating, take a look at the sex offender registry's map of your neighborhood.
The Department of Public Safety has created a searchable database for the Texas Public Sex Offender Registry.
These searches allow the public to search the registry for sex offenders registered in Texas. Parents are advised to check the registry, to help educate their family members on possible dangers in areas they visit.
Other websites provide similar search services as well:
