The US Marshals was a short-lived program in the HT-USA and non-HT USA conferences. It was squashed after an international incident.
Currently operating as a covert-ops program under the same name. The goal of the US Marshals remains the same: protect the Carebears at all cost.
Current US Marshals
Carebears are a group of US managers of unknown number who long for a US Conference in which posts are always on-topic and mostly serious. The US Marshals attempt to guide all HT-USA posts in this direction.
One of the Marshals' first projects was to hold a Summit in non-HT Belgie. Their goal was to learn from the Belgian managers how they kept their conferences so well-ordered. Unfortunately the summit turned into a major international incident (see Fallen Comrades above) after which the Marshals were forced to go covert-ops.
The US Marshals are not and never were official US Staff members. They do not have any of the authority of the US Staff and their responsibilities do not overlap. To a large extent, GMs and Mods are here to punish rogues. The US Marshals have a much more positive goal: protect and serve Carebears.
