My opinion.
Judging on the video being from Al Jazeera, I'd expect them to have some politically motivated conclusion, probably the inverse of what wabasca said.
shrek71 nailed it.
Al Jazeera (not the American division) produces some excellent journalism, especially their in-depth articles. Of course you have to know who funds it (the Emir of Qatar) to be wary of bias, but in my experience their coverage of most world events is a refreshing change from US-dominated news sources. They employ dozens of western journalists (ex BBC, etc) with very good track-records.
As for a classic example of the terrorist/freedom fighter
non-question, consider Menachem Begin whose Irgun militia blew up the Jerusalem King David hotel and 91 people (mostly Brits) in 1946. Again - shrek71 summarized it perfectly.
My post above was meant to summarize the classic Western government/media definition of terrorist.
