If an officer were to obtain evidence illegally, such as searching you without probable cause, the evidence they acquired would not be admissible in court. That's not to say the entire case would be thrown out, but that single piece of evidence would not be allowed in court. The exclusionary rule doesn't prevent unlawful searches and seizures, but it disincentivizes them by making evidence seized unlawfully inadmissible at trial. There's no reason to illegally obtain evidence if it can't be used to convict a defendant.
The exclusionary rule applies to the evidence allowable in a criminal case. One exception is the "good faith exception" established by the US Supreme Court case, United States v. Leon. This exception provides that in some cases evidence discovered in an otherwise illegal search may be used at trial rather than excluded, provided the search had been made in good faith. This means that if the police honestly believed that the search was legal (even though on further review of the facts it was not), the evidence obtained will not be excluded. This applies to officers' objective, good-faith reliance on a warrant, later found to be defective, issued by a detached and neutral magistrate. (See below link)
this is true
No, officers' field notes can be considered official evidence and may be admissible in court. Field notes document the observations, actions, and conversations made by officers during an investigation or incident. They can serve as valuable sources of information and help support the credibility and accuracy of the officers' testimony. However, their admissibility depends on the specific rules and procedures of the jurisdiction in which the case is being tried.
Scenes of crime officers (or SOCOs for short.) Forensic officers are are called to an incident, but they usually stay at the lab to analyse the evidence using high-tech equipment.
Weeks v. US, (1914) was the case that established the "exclusionary rule," preventing evidence gathered through illegal or unreasonable search and seizure of a suspect from being used to prosecute the suspect in court. This Fourth Amendment Search and Seizure protection originally applied only to federal casesbecause the Supreme Court hadn't incorporated much of the Bill of Rights to the States in 1914.Case Citation:Weeks v. US, 232 US 383 (1914)
If the officer has probable cause, they would probably tow and impound a car to find evidence. In short, yes.
Your question assumes facts not in evidence. If you are aware of officers using illegal drugs, it should be reported to the proper authorities, not bantered on a website.
Short answer: Evidence obtained illegally is inadmissible in court --Theoretically, there are several alternatives to the exclusionary rule. An illegal search and seizure may be criminally actionable and officers undertaking one thus subject to prosecution, but the examples when officers are criminally prosecuted for overzealous law enforcement are extremely rare. 158 A policeman who makes an illegal search and seizure is subject to internal departmental discipline which may be backed up in the few jurisdictions which have adopted them by the oversight of and participation of police review boards, but again the examples of disciplinary actions are exceedingly rare. 159 Persons who have been illegally arrested or who have had their privacy invaded will usually have a tort action available under state statutory or common law.
All police officers are trained in the preservation of evidence at a crime scene, but unless they are specifically trained as crime scene or evidence technicians the average police officer is merely aware of DNA testing, not any specifics as to how it is conducted.
The first rule is when your commanding officers comes into the room. When someone above the rank of your commanding officer enters the room. When a Medal of Honor winner enters the room.
The division of a police department that is in charge of searching a crime scene are a specially trained group of officers called crime scene investigators, or CSI's. These officers are specially trained to collect evidence at crimes scenes, and to process this evidence.
