Just saw this on twitter;

"BREAKING: A second device has been discovered in #NYCExplosion; a pressure cooker allegedly with wires and a timer on it #ChelseaExplosion"

I really hope it's wrong

This seems much more likely;

"Reports now are #Chelsea explosion might have been caused by chemicals in a construction dumpster at renovation site. #NYC"

I was going to say, if these weren't accidents, it seemed like the work of a terrorist who hates dumpsters or some young idiots who wanted to cause havoc but didn't know how big a bang their devices would cause.

No apparent connection, but the Times Square Theater was evacuated due to smoke.

Police say it was "The initial indications is this was an intentional act" then say "no evidence at this point of a terror connection".

Yeah - bullshit. Setting off a device intentionally pretty much implies terrorism.

Mayor de Blasio says "there's no specific and credible threat against New York City at this time from any terror organization."

Time will tell, but most of the recent incidents were committed by loner assholes whose only association with a terror group is some kind of love note to Daesh.

Not exactly. Building a bomb for shits and giggles, or to target your roommate who owes you money, is intentional, but not terrorism. Burning down a black church is terrorism; burning down your house for the insurance is not.
