Just as a bystander observing things here alone, with no real knowledge of your posting history, I'll say that it doesn't look particularly good when you make a claim about it being Islamic terror (and it may well be) because of something you saw at the scene, and then proceed - to my knowledge - not to disclose what it is you saw at the scene. And in fact seem to be going out of your way not to disclose what you saw at the scene.
Doesn't exactly make it seem you are acting in good faith. This should be obvious.
Anyhow, carry on.
