It's only murder, if there's a 'state' to accuse the perpetrator of the crime. Do areas under PA administration have laws and courts? Is interfering with anti-Israeli military operations a crime, or is killing someone for interering a crime? Sounds like a Point Of View (POV) any way you look at it.
An American soldier who deliberately shot a civilian for nothing more than arguing about the placement of heavy weaponry near that civilian's residence, would be court-martialed. But I've heard that the PA and militias associated them operate under different rules. (something like, if you get in our way we'll kill you)
So I suggest these news snippets be divided into two parts:
1. Headline and a couple of sentences, like "16-year-old boy is shot by Arab militants during argument over heavy weapons, according to initial reports by This News Source. The report was later amended to say blah, blah, blah."
2. A longer version of the incident somewhere deeper inside the Wikipedia, like on an [[Arab-Israeli Violence Timeline]] or [[Violence in Gaza & the West Bank]] article.
I wrote about an incident between Coalition troops and non-uniform-wearing Iraqis several months ago, which also had conflicting and changing news reports. That incident alone took me 3 days of research and editing, before everyone was satisfied. (I'd look it up, but I'm at work now...)
