He surveyed the scenery but suddenly looked to the area where the Texas Ranger was aiming. Did he see a glint of the scope or did he look as though he hadn't taken into account he was in the open from that vantage point?
Tanner is the essence of child abuse and having to growup too fast. Not to mention he committed a serious act and didn't feel anything, that's because when you beat and beat a child those beatings turn into hate. They turn that childs heart to ice, the only thing they care about is themselves and the person they are protecting.
Toby is the other spectrum of child abuse, being the youngest and probably not strong enough to fight of his father. He probably witnessed his brother and mother both being hit, as a result he is quite and struggles to reveal emotions. Which is most likely why his marriage failed. His rage on the punks would have been years of pent up anger that he couldn't protect his brother/mother from their father.
Toby and Tanner are the result of a damaged system that failed to protect them, then didn't fail to punish them in the end.

This is what i like about IMDB discussion boards... there's always someone to notice something which I will miss.
Nice analysis. I sometimes wonder, like you and many others decipher things from movies so easily on the psychological level -- did the creators, writers of the film actually thought the same while making it?
Talk about "something to notice" - did you see the rattle snake that was about to strike Tanner's leg just before he was shot? I think he heard the snake's movements and possibly mistook it for being further away as he looked around. Was this to tell us he going to be dead one way or another if he bullet hadn't hit him? The coiled snake was also an image in Jeremy Chalker's trailer on the "Don't Tread On Me" Gadsden flag (a symbol of revolution) over the bed where Tanner slept.
To answer the OP's question, I was looking for the glint of the scope when the Ben Foster character looked over to where the Jeff Bridges character was but did not notice it. So, I suppose that at that moment before his death, he realized that he was vulnerable from that position.
