Google Earth puts North Korea Labour camps on the map

Misleading title. Google did not mark the labour camps, a human rights activist made a map of the labour camps with Google Earth.

Just had an interesting thought: what would be the legal implications should a private party mount a recon drone effort against North Korea?<p>Assume there was some way to launch small-ish drones from international waters and fly them to such stated labor camps to take pictures/do whatever which did not include any weapons?<p>What if this effort was a decentralized grass roots activism effort?<p>Assume DPRK was to simply attempt to shoot down said drones, what other recourse, aside from doing something like attacking South Korea or something, would they have.<p>Finally what other international laws would be broken by this activity? Would the countries where the drone pilots/owners were from be either inclined or required to prosecute these activists? If so, under what laws?

Are there any other similar prison camps elsewhere in the world, or is North Korea unique?

We have prisons where people work producing military equipment, and how much one needs to go to prison?<p>How much law lobbying is done by prison owners?
