From the wiki about Thomas Muthee, the pastor seen in the video.
"Muthee and his wife returned home to Kenya from Scotland, where he had finished his graduate studies, in 1988.[3][4] They soon felt that they were "called by God to Kiambu" and after six months of prayer, research, and "spiritual mapping,"
they came to believe that a witch known as "Mama Jane" was the cause of crime and spiritual oppression in the area.[1][3][4][5][6] Muthee alleged that "top government and business leaders [were] afraid to do anything without her approval," that at least one person per month would die in a car accident in front of her "divination house" (otherwise known as Emmanuel Clinic), and that she harassed his congregation.[3][4][7] According to Muthee, soon after his followers began to pray that God would either save or oust Mama Jane,[3][4][7][8] three young people died in another apparent accident in front of Mama Jane's clinic.[3][4][7] The angry townsfolk wanted to stone her in retaliation, and when the police entered Mama Jane's home to intervene, they were apparently startled by what they believed to be a demon and shot her pet python to death.[3][4][6][7][8] Mama Jane was then questioned by police, after which she left town.[3][4][8] Since then,
Muthee has frequently referred to his witch-hunt as an example of successful spiritual warfare.[6]"
