Not necessarily. The “Miranda” rights we hear about on TV are really better understood as the “Miranda” warnings: they are statements about your constitutional rights that law enforcement must provide before a custodial interrogation. The warnings are meant to protect people from abuse while in custodial interrogation, and if an officer does not plan to question you while you are in custody, they do not need to provide the warnings at all.
The remedy for a failure to give the warnings is to keep out any statements that you made before you had them. However, if other evidence can still be used to prove the case, it may result in a conviction. Also, police do not have to give the warnings if you agree to talk to them before you are detained or arrested, and other agents, such as investigators for the Department of Social Services, do not have to give the warnings at all.
If you have questions about your rights, call 540-951-8329 to set up a consultation.
