Her friend's boyfriend gets fooled that some random dude with neck tattoos, civilian clothin and no car is a deputy. Good god that was *beep* stupid. I would have punched him right in the face when I went to hand him my phone.
I still thought the movie overall was ok but if that scene played out different it would have been better.
I don't know where you live, but out where I used to live there were some rural police who could look . . . pretty rough when they weren't in uniform. During emergencies (like car accidents or trees downed on our back roads) I would often see off-duty police or firefighters show up in their civilian clothing.
And psychologically, once someone identifies themselves as an authority it is hard for a lot of people to get their head around the fact that the person isn't who they are claiming to be. We can't have it both ways as a society. We can't demand that people never run from police, always follow police directions, etc and then turn around and say that people should punch someone in the face if they suspect they aren't really police. The killer anticipates the question by claiming that his gun and badge were stolen. And by acting suspicious of the boyfriend in the beginning, the killer makes the boyfriend think more about his own innocence than questioning the killer. It's frustrating to watch, but it makes sense to me.
He wasn't really fooled, hence the large rock in his hand that he hid behind his back.
shareHe was suspicious from the beginning, but he only really understood when the earring the killer took from his girlfriend fell on the floor.
That is my opinion, it is mine and belongs to me, and I own it and what it is, too.
