Your last part sounds like one of Bruce Schneier's Movie Plot Terrorist Threats. Mainly in the sense that weaponized biologics (threat-du-jour: Ebola; Anthrax) could already be dispersed by consumer crap coming from anywhere in the world, eg. a sticky tape containing Anthrax spores sneaked into the CPU cooling-fan assembly plant and stuck inside the vent so that every time your CPU fan runs it spews out spores. For Ebola, you just mix a few drops of the bodily fluids of a patient who died of Ebola into one of those fancy tetra-pack coconut juice boxes using a few syringes and have instant Armageddon. All of these are purely fictional scenarios, of course, but hey the three letter government agencies need to scare the shit out of the public to get increases in their funding now don't they!?!
