The aforementioned cases were disliked by conservatives because they provided legal protection for suspected criminals against police misconduct. In the Miranda case, Miranda was interrogated constantly by the police until he confessed. However, he was not made aware of his rights and his case was thrown out. This resulted in the development of the Miranda warning ("You have the right to remain silent...").
Escobedo faced a similar situation, as he was accused of murder but was prevented from seeing his attorney and not informed of his right to remain silent.
