Do Not Cross

We see, every time there is a criminal incident, there is a yellow ribbon that says do not cross.

That is the police line that no one can pass or enter by unauthorized persons against the scene. Since the police line was installed, the crime scene was declared a status quo, the status of what was or was the exact moment of the case. Must not be entered, tampered with, held without law, which is justified by police forensics.

But in fact, many people enter at will, and stepping on, moving stuff, even making dirty inside her, but many people do not know

It may be useful to know the first action procedure at the following TKP:

1. Contact the police as soon as possible. Before the police arrive, make sure the scene is safe from harassment or harassment from anyone in order to maintain the authenticity of the scene
2. After the police come and install the police line, make sure the crime scene remains genuine before the crime scene is completed
3. Never hold any evidence or objects within the crime scene, without gloves, or remove the location of the evidence outside the procedure.
