A few years ago, some foreigners entered a subway depot in South Korea, drew graffiti, and left the country before they were caught.
South Korea put a notice on them on Interpol. At least one was arrested (at an airport in Romania), though I couldn't find any follow-up article on what happened to him. I hope he got to tour the inside of a South Korean jail.
A society should be willing to put resources to protect is public infrastructure. In the long run, it will also be cheaper than fixing the same thing a hundred times, everyone enjoying second-grade service, or both.
