I can't point to anything specifically incorrect about this reporting. But you have to take a lot of primary-source-based reporting on faith, and why would I trust a source that has such a non-neutral track record?
We'd all be better served by sticking to sources that don't have obvious conflicts of interest.
Edit: I want to be clear that I don't have any specific evidence that the article contains falsehoods, and I'm not excusing any of the conduct alleged in the article. I just think Al Jazeera is a terrible way to start a constructive discussion, given its reputation.
