Oh je... Paranoid Park.
I don't have the same opinion like Annie. I think Alex is to blame for the death of the security man. Because he has beaten him in the stomach with his skateboard, he fell off the platform on the rails. (Der Security Guard ist nicht vom Zug gefallen!) If Alex would have told this the police, they would say that he was guilty. It's not right not to notify the police about the accident, but there were fatal consequences concerning Alex, so I can understand why he didn't inform the police. If I had been in this situation i would be as desperate as Alex and surely everyone can understand this.Though I just read an extract from the text, I think the book is written very realistic, so it's fun to read.
