<human>: What's an argument for and against using a GPS system to find a missing person?
<bot>: Argument FOR using a GPS System to Find a Missing Person: 
1. Using a GPS system can help narrow down the search area, making it easier to locate the missing person.
2. GPS systems are accurate enough that they can be used in conjunction with other methods of tracking like cell phones or vehicle tracking systems.
3. A GPS system can provide real-time information on the location of the missing person, allowing emergency responders to respond more quickly.
4. GPS systems can also track the movements of the missing person over time, providing useful data for investigators trying to determine what happened to them.
5. Finally, GPS systems are relatively cheap and easy to use, so there is no reason why everyone shouldn’t have access to one.
