B.S.A.A. Stands for Bioterrorism Security Assessment Alliance. The B.S.A.A. is a national security agency which operates both in the United States of America and Africa and possibly other regions of the world. The B.S.A.A. was developed in order to protect the human race from Bio-Terrorist attacks like the one which occurred at Raccoon City, September 29, 1998 (Raccoon City is a fictional midwestern American city) which was believed to have been overtaken by ‘Zombies’ or ‘The Living Dead’ due to Umbrella’s secret Bio-Weapons.
