The brutal murder was committed by a neighbor who lived some 130 m from their homes. Investigations are ongoing with more charges from past cases involving the murderer coming to light. And with it, the nation's police are being scrutinized for incompetence.

In response on Wednesday the National Police Agency announced its plan to install GPS or Global Positioning System on all cell phones nationwide while introducing Radio Frequency Identification Tags.

Under the current law, the police do not have access to phone GPS and they say this law needs to be revised. Only 20 percent of the nation's mobile phone users have GPS installed, making it difficult for the police to track the location of people while they are being abducted.

Experts say the plan will have to overcome issues like cost, which falls directly onto customers, and invasion of privacy.

Radio Frequency Identification Tags are devices that can be attached to a bag or clothes and give out personal information via high frequency to sensors. This is being marketed as an additional safety tool for parents of children who are out without supervision.

The location and an imagery taken by a camera device inside the tag keep track of the child, communicating directly with the parent's cell phone.

The idea comes from Japan, where the system is being tested at two of Yokohama's elementary schools due to the country's experiences with child kidnapping cases.

Whether the new devices work or not, parents are impatient with the system, wanting assurances and direction on how to keep their family safe in an increasingly unsafe world.
