He was clearly influenced by Islamist dogma, so in that sense he was an Islamic terrorist. Fortunately he wasn't particularly clever or organised so he wasn't very effective. A number of hostages escaped so clearly he didn't have a cohesive plan and it seemed he acted alone.
The situation he generated could have been worse, but it was bad enough for those who were killed.
The disturbing and unanswered question is "how many more like him" ?
When those 600 odd AFP made that raid some months ago, there were at least 200 Muslims protestors in the streets and you can bet your boots the AFP would have them well photographed.
I thought at the time it was a good ploy by the AFP to drag them out of the wood work and it worked so well.....they received the desired affect......I did make a comment when it happened.
