John your assertions of "violence in Freetown" and "bad blood between factions" is basically trash. You can pick up any of the daily papers and read about "violence" somewhere in Freetown involving the two major political parties, SLPP, Sierra Leone Peoples Party, and the APC, All Peoples Congress, which is the ruling party. The violence you speak of usually happens around the Clock Tower or Congo Cross and involves young men of both parties fist fighting while fueled on by a little too much palm wine. It is very rare that weapons are involved. The Sierra Leone Police (SLP) round them up and the appear before the Magistrate the next week or so. Sierra Leoneons take their politics very seriously, and back their parties with a bit too much zeal sometimes, but to assert that it is unstable is simply not true. There is plenty of fire power in the region between the S.L Army and the U.N., and it would be extremely unlikely that a coup would be able to take place. I said it before, President Koroma will win by a landslide and it's business as usual.
