When It Comes To The Fourth Amendment And Searching A...

When it comes to the Fourth Amendment and searching a person’s car or their person, there are a few factors to take into consideration. In order for an officer to search an individual’s car, they must have consent, otherwise the search is unreasonable and whatever evidence seized could be inadmissible in the court of law. However, it is possible to conduct a search without consent and seize evidence without a warrant but there ought to be probable cause or reasonable suspicion. The two differ in the sense that reasonable suspicion is based off past experiences and expertise. Probable cause is needed for a search to take place; conversely if there is no probable cause but an officer has enough reasonable suspicion, they still are allowed to†¦show more content†¦On the other hand, in Minnesota v. Dickerson (1993), if an officer can readily identify an object from a pat down, they can use their discretion and experience and retrieve it if they know it to be true. If they are unsure and take it, whatever was seized is inadmissible in court. In legal terms, this is known as the plain feel doctrine. This allows a police officer to seize objects during a legitimate pat-down search if by plain feel he reasonably believes it to be contraband. Just because the plain feel doctrine has been established does not granted officers the right to touch, it simply permits an officer to interpret tactile sensations to identify an object during a pat down (Poulin, 1997 pg. 23). There is a strong correlation between the Fourth Amendment and racial profiling. I asked a police officer what they believed was the main reason for a lawsuit against an officer and they said violations in regards to the Fourth Amendment followed by failure to act. Take the United States v. Brignoni-Ponce case for instance. A police officer pulled over a drive that looked to be Mexican because he believed them to be an illegal immigrant. The problem was that officers were roving the border and stopping individuals for no reason other than to see if they were illegal immigrants. The Fourth Amendment held that a patrolman is prohibited to crowd the Mexican border just to stop andShow MoreRelatedU.s.
