Even if we could take the assertions of the accused and the girlfriend at face value, there's the problem of "credible threat." If I start with the claims you attribute to them, I still can't make a credible case for a couple of big guys stomping a guy while he's out on the ground. All I can say is, if a friend and I did that to somebody—unless our opponent had been attacking me with a lethal weapon that he still possessed—I'd rightly be indicted for attempted murder.
Do you have a link that backs up the story of Steinhauer being a danger to society? I've seen accounts that said he danced with the girl; that he groped the girl, or the guys thought he had, but the girl says he hadn't; and so on. The closest to your analysis I can find is on Pravda.ru, which has typical posters saying things like this concerning the story, which I'm presuming you don't endorse:
"The faggot was a jew, you can't touch the gods without the whole jew government come down on you."
The only credible threat is the threat that Kovacevic would get railroaded in court given the fact that the other two who did the beating got only 10,000 bail and he got 100,000. Sounds fishy to me. And given that the yellow scandal mongering press is trying and convicting Kovacevic in print is another reason for his getting the heck out of here.
Who said anything about Stinhauser being a threat to society? Need a pair of reading glasses maybe or just spouting things off the top of your head?
Your weird analysis befits the Natl. Enquirer and the NYSlime machine.
