That's happening; holland takes on Belgian prisoners. Or at least they did, then did not, then did, I'm not sure where it stands right now. But definitely happening :)

Belgium has an abysmal track record when it comes to prisons. It's been repeatedly convicted for treating prisoners like cattle, for putting psychiatric patients in regular prisons without treatment etc.

Sending some prisoners to Dutch prisons (including a prison boat, iirc) is one of the best things that's happened to the Belgian penal system in years. Sadly it's only a temporary relief, and it's been cancelled (and resumed) several times.

The programme was stopped because Belgium finished building new prisons.

When was this? Last I heard there were still over crowding issues.

They are importing prisoners from Norway too :P

According to the article, they are doing exactly that (but only as a partial "solution").

Played a lot of Sim City? :)
