Most crime labs in the United States are funded and operated by the govern- ment and provide services free to police and prosecutors. Great Britain, how- ever, uses a quasi-governmental agency that charges fees for its services and keeps any profits it makes. Suggest potential strengths and weaknesses of each system.

the correct answer is 2 and 4

the limb fractures are among the most common fractures. open fractures are comparatively more dangerous. the injury patterns are dependent on many factors, such as the age of the person, and mechanism of the injury. the closed fractures of the limbs if left untreated may lead to a significant amount of the blood loss, which may be life-threatening for the person. approximately 1000-1500 ml of blood is lost in the close fracture of the femur, and 500-1000 ml of blood is lost in the closed fracture of lower part of the limbs.
