Police Hologram in South Korea Proves Effective

In South Korea, a police hologram was installed in a park to reduce crime rates, and it worked. Real cops are thrilled - the number of crimes has actually decreased. And even if potential criminals take a closer look and see that it's just a virtual scarecrow, they don't want to break the law under its watch. There is another theory among users: the wrongdoers think it's the ghost of a police officer patrolling the park, and they avoid it.
