I am sure they all had the “potential” to explode(contained some quantity of explosive) but were they designed to explode and just because they had a POS digital clocked taped to them don’t mean squat.
The bomb folks treat them all as deadly and right fully so which is what the FBI talking heads are saying, not that they were deadly not deadly whatever.
How the info gets sent to us poor slobs in the public is and entirely different story
Initially the reports were that they contained black powder.....
But officials seem to be backing away from that claim....
It may be an inert powder.....
Even if it was black powder the entire device looks like it was built by Wiley Coyote..... it just needs an “Acme” stamp on the side
