Chris Plante talked about this too. I heard that these devices didn’t have blasting caps.
They do not have blasting caps, triggering devices, power supply, appropriate wiring, a working prototype, or explosives. They are toys, not bombs. I get it that appropriate authorities must treat them as potentially lethal, right up to the point they are examined. After that they are evidence of possible forensic nature. My guess is Antifa half wits.
