The demand of police officers who got the order to order a court order order became somewhat vague. The police are more likely to decide not to acquire a search warrant if you think that there is a reason to believe that there is a possibility that drugs are at home. When the US Supreme Court judged that there was the possibility of ruining the evidence thinking that the police smelled marijuana, they decided that there was a reason to forcefully enter the house without an investigation warrant.
Evidence was collected immediately after the crime. The police are responsible for ensuring the safety of crime scenes and preventing evidence from being destroyed. When the evidence team arrives, they carefully mark each evidence, measure and shoot everything and shoot. This is the beginning of a series of evidence. Everything that can be gathered from the site is placed in a sealed package with the following information: case type, date, collection location, item description, police case number, serial number or clothing identifier, collector name And identifier information, and where the items are delivered for analysis. Chain of custody forms are often displayed on the back of the package and each person handling the package must sign their name, date and say why you own it. The book "Hidden Evidence" by David Owen explains, "In most cases, the most important details are revealed in the first search."
Through the search warrant of the book, CSI began training at the crime scene. He follows a predetermined path that may contain the minimum amount of evidence that can be destroyed by walking through it. During the first training, he quickly recorded the changed details over time: how was the weather? When is the time of the day? He describes what eye-catching smell (gas? Decomposition?), Sound (waterdrops? Smoke alarm beep?), And something that seems to be inappropriate or missing. Is there a chair leaning against the door? Is there a pillow on the bed? This is also a time to identify potential hazards such as gas leaks and to solve the body quickly by protecting the body from stirring dogs.
