I keep hearing that this is an attack against the free press. This seems to be because one of the bombs went to the CNN headquarters, addressed to John Brennan. But it's ridiculous to suggest that CNN was themselves being targeted. Every package has been addressed to an individual, and every individual is a prominent figure in liberal politics, or prominent voice of liberal ideology, who has been targeted for criticism by Donald.
To identify CNN as a target is grasping at straws. If the perpetrator wanted to target CNN they would have sent a device to an exec, or to a handful of CNN's on air personalities. The infinitely more plausible inference is that the perpetrator was aware Brennan has appeared on the network, possibly mistakenly thought he was a regular contributor for CNN, and couldn't figure out any better way to address a package to him. CNN's involvement in this is that of an unfortunate bystander.
But CNN and MSNBC are latching onto this in order to make a more sensational story. Doing this feeds into the "fake new" narrative that Donald loves to weave. It seems that nothing has been learned.
