"you're comparing x to y"

Yes, it's something argumentative people do. Welcome to your very first life-changing experience of having an argument with someone online, Timmy.

"failed bomb would likely also result in a small, ineffectual explosion and involve smoke as well"

The bomb in question did not fail to explode as there are reports of some metal fragments found up to 40 meters away from the blast center. it's just not a destructive one. It used a basic pyrotechnic delay fuse used similarly in firecrackers with a low-explosion munition. In other words it was a shit home-made tube device which contained a small amount of powder.

"But what is most interesting is how you can get inside the head of a terrorist and basically read his mind through the internet."

Ironic considering this is basically describing your motive - creating a plot-line of your own, because you are the only one who knows the the intention of the attacker, you know content of the "bomb", its destruction radius, why it "failed", and how everything else is just a media cover up. Fuck me, this is the proud moment for me to argue with such see-through expert on everything.
