Un tueur dans mon quartier

The early "warning signs" that the acquaintances and friends of the family were pointing to in Episode 4 of Season 1, are considered normal for most parents in all places and time periods. Recording your fully clothed sleepy teenage son or daughter waking up, or monitoring their phones and boyfriends is considered creepy from a parents point of view? The dad jokingly saying "she smiled at the customer, she's in trouble," is a warning sign? Ridiculous. At this point, any few seconds captured on home video can be considered "a warning." One should also note that the dad was an immigrant from Egypt, whose kids were becoming Americanized. This isn't an excuse for murder, but not necessarily a "devil warning."
