During an investigation, you have rights under the Fourth, Fifth, and Sixth Amendments to the United States Constitution.
Fourth Amendment
Under the Fourth Amendment, you have the right to be free from unreasonable searches and seizures. Although there are exceptions to this rule, law enforcement generally cannot search you or seize your property without first obtaining a warrant.
Fifth Amendment
Under the Fifth Amendment, you have the right to remain silent after an arrest. You also have the right to an attorney when law enforcement questions you.
Sixth Amendment
Finally, the Sixth Amendment gives you the right to an attorney during all stages of prosecution.
You have the Sixth Amendment right to counsel from the time the government begins adversarial criminal proceedings, through a preliminary hearing, indictment, or arraignment, and throughout the remainder of your case.
