This video is grimly fascinating: it shows the Munich spree killer walking around on the top of a parking garage.
The guy filming him (or someone close by) begins screaming insults at the killer, and the killer responds and gives a few reasons why he is doing what he's doing. In a Youtube comment, Scalpelli provides a pretty good translated English transcript of their dialog:
Some English translations floating around on here are wrong. Here's the correct one:
Balcony Man: "You fucking asshole you…"
>Shooter: "Because of you I got bullied for 7 years…" (referring to Turks)
Balcony Man: "You wanker you. you're a wanker"
>Shooter: "…and now I have to buy a gun to shoot you"
Balcony Man: "Yeah, you know what? Your head should be cut off, you asshole!"
>Shooter and Balcony man shouting at each other
Balcony Man apparently to people filming: "He's got a gun here, the guy has one"
>Shooter: "Fucking Turks!"
Balcony Man: "Fucking wogs" ("Kanake" is a mean term for Turkish immigrant workers)
Balcony man to someone else: "EY! HE'S GOT A GUN! He has loaded his gun! Get the cops here!"
>Shooter: "I am German."
Balcony Man: "You're a wanker, that's what you are"
>Shooter: "Stop filming!"
Balcony Man: "A wanker is what you are, what the fuck are you doing?"
>Shooter: "Yeah what, I was born here!"
Balcony Man: "Yeah and what the fuck you think you're doing???"
>Shooter: "I grew up here in the Hartz 4 area. Here in the Turk-region, in the Hasenbergl" ("Hartz 4" = social welfare benefits in Germany / "Hasenbergl" = district just next to the shopping mall)".
>Shooter says he was depressed for some time and got clinical treatment ("stationäre Behandlung" here usually refers to being under treatment at a psychiatric clinic).
Balcony Man: "Yeah treatment, you belong in a psychiatric clinic, you fucking asshole."
>Shooter: "I didn't do anything wrong. [unintelligible] Just shut the fuck up man!"
Balcony Man: "You wanker you"
Balcony Man: "HEY! HE'S ON THE UPPER FLOOR HERE. YOU IDIOTS"
Filming man goes into cover, shooter starts firing.
Balcony Man: "You're not quite right in the head / You're fucked in the head you wanker"
Unknown voice (police?): "EY, go over there!"
Balcony man: "You fucking asshole, you're fucked in the head!" – literally translated though he says "They shat into your brain", to which the shooter replies:
"No they didn't, that's the thing, they didn't"
