The black and white image on the "device" more closely resembles this World News Bureau emblem, which looks like the ISIS flag but is not the same: https://www.worldnewsbureau.com/
The whole charade seems like total political theater though, without a doubt.
None of the "devices" detonated, ALL were delivered within 24 hours of each other even though they were mailed or couriered to locations spanning thousands of miles... and they were all sent to high-profile democrats or "establishment" individuals who have spoken out against Trump (arguably the most publicly-hated president ever in US history). This thing reeks to high heaven.
PS I am now following you firstamendment, thanks for sharing this.
