The press is regurgitating what the Austin police department was slow to report (about the threat of opening strange packages found on your porch).
Apparently they have the materials from several packages and have concluded that they weren’t delivered by USPS, FedEx et al.
There is some suspicion that the bomber set them off local (while watching from within the neighborhood).
You can't honestly expect the police to to give a rat's patoo about mere civilians. They are too busy navel gazing over whether they have triggered some feminist SJW by calling her "she", rather than what it self-identifies as.
Well, it WAS dressed as a 6 foot vag, but it should be obvious, even to a neo-nazi gun nut...
