Spoiler...Why didn't Johnson....
Why didn't Johnson identify himself as a policeman when he found the girl? Instead, he takes his coat off, keeps saying "it's all right" and "I'm not going to hurt you", then gets on top of the girl and pins her arms down. Sheesh, no wonder she was scared to death. If I was her I would have been scared to death, too. Also, as a couple of other people have stated, he looked to be almost enjoying caressing her hair and such. The way he treated her almost made me sick. It was disturbing enough that I basically was just kind of dumbfounded through the rest of the movie.
The first thing any other cop, or any person for that matter, would have done is cover her with his coat, not take it off and get on top of her.
