The officer asked who he was and how he knew the suspect. He responded that she was his daughter in law. The arrest proceeded, the child was taken by the father in law. The next night, near midnight, the same officer came to the home with several others and arrested the man under the charge of obstruction from the previous days events, then the same officer entered the home without permission and announced to the residents his presence and that they were arresting the gentleman. The question is what justification is there under these circumstances for the charge of obstruction.
