Zero proof of a bomb, and even less logic behind the idea it was.

a planned attack is what im saying. it doesnt have to be an actual bomb dropping from a plane.

You're really good at spotting things, my friend.
Are you perchance the lovechild of the famed Sherlock Holmes and fabulous Hercule Poirot?

it doesn't take a Sherlock to spot your multi.

Yes. Well done. I knew you were good.
It would take the combined DNA of Holmes and Poirot.

If this were a planned attack, why wouldn't the attacker(s) just plant a small charge in the ammonium nitrate itself, setting it off directly? Why start a fire in the adjacent fireworks storage facility, which gives people time to evacuate the area to an extent?

what makes you think this? besides obviously the idiot trump saying .. fuck who knows what he says.
but implying that it was an attack.. where is this magical information?
