I just can't seem to remember what this movie's called.
All I remember is that it's from around 2000-2009. The bad guy puts up surveillance cameras in a woman's house, he becomes friends with her, helps her carry grocery bags etc.
Apparently he kicks her husband off of a horse too...
EDIT: Well, it's an English speaking movie, the husband of the family works with computers somehow, and the bad guy wants his help to steal some money. He installs some cameras in the family's home which the police then finds.
It's a thriller/drama.
