The correct answer is: the law enforcement officer taking command of the scene and setting boundaries so that uninvolved persons cannot come on the scene, thus keeping both people and evidence safe.
There are a few steps that should be followed when it comes to investigation of the crime scene, So, basic crime scene protocol includes:
1. Establishing the scene dimensions-establish an area that contains all relevant physical evidence.
2. establishing the scene security- controlling the person who enters or exits the scene,
3. Making a plan, communication and coordination- developing a theory
4. Conduct a primary survey- identification of potentially valuable evidence,
5. Process the scene-collecting the evidence
6. Record and preserve evidence-to make sure all evidence is accounted.
