Sangha Town was no impenetrable fortress, but it was virtually impossible for an outsider to sneak in with a gun.
The people at the foot of the hillside were spotted the moment they arrived because the area around the boss's house was a priority zone for unmanned aerial vehicles. A few large living people poking their heads out on an unprotected hillside was just too conspicuous.
If they managed to get near Sangha Town, they must have been black, and definitely not from the south.
The south of Sangha Town was already sealed off by P·B, all to create a suitable battlefield outside the law.
The likelihood that these people approached from the direction of Capital Bangui in the west was high, because Joe Ga lacked control over that direction.
There had been some disturbances from the direction of Bangui before, but Setaka died too quickly, and then there were no more reports.
