Why Not Call the Cops?
I've always liked the film, but it's hard accepting the refusal by the mother, when either Gloria or the granny suggested the police should be called. She just says NO! Her family faces extinction and she doesn't want to call the police to just possibly, get some protection in time? She doesn't even give a reason.
They'd rather just play at being tethered goats.
It was of course convenient for the film's plot.
