What does this quotation say about how miranda’s confession was made?

Miranda incriminated himself without knowing that he could refuse. I hope this helps. ;-) 

He was probably very upset and disapointed and mad. all at once. so he probably wanted to show his disapointment, angryness, and depression. he didn't think of the affects due to the minor issue thst he has gone through. sorry if it doesn't . but i am trynna people.
