o understanding what is evidence, is everything that seems relevant to a case admissible, no. We can look to the United States Constitution and see that evidence uncovered regardless of how damaging done by unreasonable (unwarranted) seizures and searches can not be admitted into a court of law. This protection is granted in the Fourth Amendment of the United States Constitution. So one may wonder if evidence must be admissible to be evidence then how is admissibility determined?

Officers who stop a car and look inside do not conduct a search under the Fourth Amendment. If the officer sees an object they reasonably believe is evidence of a crime, they have probable cause to seize it.Therefore we can readily ascertain that evidence is information (any kind of information) gathered...
