The purpose of this initiative was to define and analyze the current situation with respect to both legal and illegal firearms in Colombia, determine the role they play in the exercise of violence, and analyze the institutional framework that Colombia has to control arms. Likewise, we reviewed the country’s participation in the different international agreements and instruments. The analisis expounds the strengths and weaknesses of arms handling in Colombia. An in-depth diagnostic of the institutions directly responsible for the handling and control of arms shows that Colombian institutions adhere to high control standards, ranging from the regulation and monitoring of arms in the hands of private citizens to strict protocols for the control of arms held by the Government’s different security agencies, such as the Armed Forces and the Police. The Colombian Military Industry has strict regulations concerning the marking, transfer, and sale of arms.
