what is a drop gun cop

A drop gun cop is a term used to describe a police officer who carries an unregistered firearm, which can be used to plant on a suspect in an officer-involved shooting to justify the shooting/killing of a possibly unarmed suspect. The term "drop gun" is also used to describe a firearm planted by police officers to justify a shooting. However, it is important to note that the use of "drop guns" by police officers is extremely rare and is not a normal part of police culture.
