If you can tell that something is missing, it may give a clue to who may have started an arson fire. Missing jewelry, missing artworks, and missing teddybears may lead to different perpetrators. And if nothing is missing, then perhaps a fire isn't arson at all (or an arsonist was out to get the family.)
If a bomb has exploded on the 10th floor of a government building and dust and debris are falling from the building, it is a priority to move the bystanders who have begun to gather at the scene. This can be accomplished using police or other authority figures.
Just be yourself .. if you are infact scene it should come natrually
Yes, yes you should.
should you not try to move accident victims from the scene.
If you are an investigator, you should know how; it is part of your training.If you are not and you do not know, you should not be moving anything at a crime scene.
If you are extending a scene, the you should be careful about the existing tone so as not to change about a character.

Well, if you expect an answer, you should clarify WHAT scene you are talking about.
