Are Dingo Attacks a Forensic Question?

Lindy chamberlain is accused of murdering her baby daughter. She was interviewed by police and gave a forensic answer to their questions about the case. The prosecution asked why she didn't break into the house where it happened, but lindi said they would have found out if there had been any problems with the lock. LZ Granderson says this type of questioning drives him nuts. He believes that people should be able to provide an alternative explanation for what may or may not have happened in such circumstances.
