the 'you don't live here' concept, doesn't hold water. while they may not actulay live 'here', what they do have is real experience of watching this go on somewhere else and are only trying to pass along what everybody already knows is going to happen.

well,, i believe the 'planners' have 'planned' something, but the GOB has not accepted it,, or some shit.
it is a disaster going to happen.
imho
