Bombs...or fake bombs as it's looking more and more likely that's what these things are...are like hurricanes and Schrodinger's cat....the communist fake news can view them as anything they want them to be before the box is opened and we see who actually did it.
Given that the majority of the major news networks are communist...well...we get to be entertained by their blathering on about how evil the right is for sending these things. Once the box has been opened and we see that some insane communist sent these things out as a false flag or Reichstag fire incident, the story will be dropped like a hot rock, all the damage to the right having been done and no blame or responsibility ever being laid at the feet of any communist perpetrating such ever being dolled out.
All designed to get out the communist vote.
