The question of time is frequently the first subject covered in a cross-examination. If the investigator cannot be sure of the time of events, he may lose credibility on the rest of the testimony. The subject of time may very well be the basis of an alibi. Note taking forces the investigator to slow down. It thereby sets a calmer tone for subsequent events at the scene, and also causes the investigator to pay attention to details in order to record them in the notebook.
Extreme care must be exercised to preserve and protect the scene, because even the smallest detail can suddenly assume vital importance in the case. Failure to implement proper crime scene techniques may irreparably damage the investigation. A complete description of the crime scene and surrounding area are vital. Although some of the points may seem quite obvious, things are sometimes overlooked, especially during this initial phase, as you attempt to cover all the bases. Note doors, windows, furniture, and identify entry and exit points, note if anything looks out of place. At this point you are present to evaluate the entire crime scene and surrounding area. During

Despite just being shows, one wonders whether these popular shows have skewered public perceptions about forensic evidence in real court cases and have impacted the outcome of court verdicts. The CSI Effect, explained by Kim, et all, was named after the television show
Evidence analysis and ranging is the most crucial stage of investigation. The success of the case exposure lies in the gradual evidence research and collecting prior to the laboratory analysis. The CSI systematically makes his way through the crime scene collects all potential evidence, tagging, logging and packaging so it remains intact on its way to the lab. Depending on the task breakdown of the CSI unit he may or may not analyze the evidence in the lab.

Collection of evidence is usually a term designated to refer to the collection of physical evidence, government agencies such as police or environmental protection departments will have their own methods for the collection, storage and conservation of physical evidence and it is the responsibility of forensic personnel to adhere to these set guidelines. General principles which are shared amongst various agencies include, the creation of contemporaneous notes, recording the collection of evidence via photographing, videotaping and/or audiotapes, preserving the crime scene by sealing off the location and only allowing designated personnel to enter, avoiding contamination of the crime scene by investigators through the use of full body covering and also preventing cross-contamination with the scene and any suspects.
Collecting evidence from a crime scene is a crucial aspect of solving crimes. Before evidence can be seized, there must first be a court order approving the search of the crime scene and the seizure of the evidence found at the scene. Standard protocol for officers is for them to always use latex gloves, avoid plastic bags, double wrap small objects, package each object separately, and to collect as much evidence as possible. It is better to have too much evidence than to not have enough. There are countless amounts of evidence that can be found at a crime scene.

When there is a criminal case, are a set of guidelines a criminal investigator should follow when conducting a preliminary inquiry.

They will need to take care of any injured person or people that may need emergency care. Check to see if there are any witness seen what had happen. Make sure the crime scene is safe and secured.

Preliminary investigations square measure most effective once the officer views the work as a method rather than as a series of easy mechanical tasks. This approach additionally provides a guide for initial responding officers to select acceptable initial investigatory procedures. Rarely are two crimes identical; thus, there cannot continually be an identical set of procedures to follow in every and each case.
