The International Crisis Group wrote in 2011 that 'Over 4,000 officers have been trained, including the armed Emergency Response Unit (ERU) and the specialised Police Support Unit (PSU). 623 (15 per cent) of these officers are women. At a ratio to population of 1:850 and with 65-70 per cent deployed in Montserrado county alone, there are clearly not enough officers to cover the whole country. The ERU, set up in 2008 to combat spiralling armed robbery, is functional and appears efficient, though based on revised needs assessments, it has only 344 officers instead of the originally targeted 500. The PSU is meant to have 600 members by December.'
