1 death, 151 people in quarantine and 30,000 trapped...
Its seems like TPTB are TRYING to get a pandemic started. So many new diseases in so many places all at once. I rather suspect Pandemics are harder to achieve than most realize. Even the Flu doesn't hit everyone, and it doesn't kill you. If the Flu did kill you , you can bet the other humans around you are ever so much more careful - limit contact - wear masks, wash their hands more, etc. They are probably very hard to start in a population- another reason for bring in diseased children from abroad.
If a pandemic starts, It implicitly allows martial law as quarantines are established. Your neighbors don't help you as you are taken away to a facility because you are suspected to be infected - it doesn't matter of course if you are sick or not. If you are an enemy of the regime, you are taken and put with the sick people, and expected to die.
They can accomplish this type of purge/round up without "coming for the guns" - which of course are rounded up over time because no one who goes to the FEMA camps for "treatment" ever comes back. Basically at this point if SWAT is on your lawn, you should be shooting at them. There is no point in talking, they would only present you with the lie of the day anyhow, and if they gain access to you or your home you are dead anyway.
