Corporal Tan was also promoted to the rank of Sergeant. The case made front-page news in the local media, and led to the public writing letters to the press expressing concerns over the possibility of police procedures preventing the officer from defending himself adequately. Existing police procedures forbade officers from drawing their weapons except when there were imminent signs of danger to themselves or others. Hoi's death contributed to a review of these procedures, which now permit officers to draw their weapons based on personal judgement and assessment of the situation presented before them.
