Legal Question in Criminal Law in Missouri

To be clear, an arrest by itself does not trigger the necessity for you to be given a Miranda warning. This is a common misconception. You are required to be read your Miranda rights prior to a custodial interrogation. An arrest satisfies the custodial part, but the you have to determine if you were subsequently interrogated. And an interrogation is something more than the officer just asking biographical information (name, birthdate, etc). And even if you were interrogated without being read your Miranda rights, it doesn't invalidate the arrest or somehow cause the charges against you to be dropped. In that situation, your lawyer would use the fact that no Miranda warnings were given to try to supress evidence against you obtained as a result of the interrogation. I would suggest you hire an attorney because criminal charges are serious and the laws can be very tricky to understand.
