SA Police show how to ensure Haloween doesn't become horror story Trick or treat in safety this Halloween with an easy checklist from SA Police. SA Police are showing how children can ensure Halloween provides safe fun. POLICE are urging parents to keep their children safe on Halloween and have issued posters to identify houses taking part in the celebrations. The posters, available online, can be displayed by residents on their doors to indicate whether or not they welcome 'trick or treaters' for the October 31 event. An SA Police spokesman said there also was a act sheet to help parents keep their children safe and instruct them them how to behave. "The Community Relations Section has prepared a comprehensive fact sheet containing tips to keep your 'little monsters' safe, and to promote respectful behaviour towards residents who don't wish to participate," the spokesman said.
