Explanation:

When you and a your partner or team are approaching a crime scene, there are things one should know beforehand. These things are:

1)  Identifixation of the area of focus on the scene and determining the area which might contain a necessary or relevant evidence.

2) Protecting the crime scene using a tape to restrict movements.

3) Determining the nature of the crime, pointing out any threats that night tamper with the evidence, assuming if other resources might be required and discussiiwith your partner or team.

4) Identifying any evidence on ground and taking photographs of each of them.

5) Processing each of the evidences after collection.

6) Doing a quick check around the crime scene and leaving nothing behind.

7) Record all evidence found on the scene and begin a clear line of investigation.

ii) When you and your partner happen to get in touch with a wet evidence then it should be dried and put in a paper container because paper containers prevent the evidence from degrading and so, putting it in a plastic container before transferring it to a paper container is absolutely crazy. Rules for biological or wet evidence is to refrigerate wet or liquid evidence and freeze dry evidence.

One should have in mind that protecting an evidence can help identify the culprit through DNA samples. DNA samples have done a great job in identifying criminals in murder or robbery cases.
