Lets say that the situation was that this person A was stopped by police and they told this person A that they needed to search their car, without any reason. I am, possibly incorrectly, assuming that this officer knew that person A was uneducated of their rights and therefore out of fear knew person A would agree to this search. Also, unrelated to this previous statement, would any prior infractions or minor brushes with the law give officers the right to search our car or would that not matter?
