Personal opinion.

These coincidences are, in my opinion, too numerous to not be seen with great suspicion, besides this place is controlled by the United States, a country that has held the world power since World War II, therefore it has been revealed some secrets. Even now there are people who have paid a lot of money for exposing the mysteries of Plum Island.

Maybe some of the events described previously are only a conspiracy theory or just hearsay. But, on the other hand, I think there may be the possibility that these events are real because of the evidence, and I think the more certain evidence are the cases of disease that have ocurred near this mysterious island, and also the interviews that have been made to some employeers, and even victims of experiments of this laboratories. 

It is true that the research program of the laboratories has very low standars of safety and levels of biosecurity, because they have revealed cases of sick workers who where denied medical assistance from their employers. 

Finally, I think if all this is true, and taking into account that Plum Island is not the onle place that has laboratories for this purposes, it must be a future plan of population reduction caused by a biological war which is in the hands of perverse minds that has the world power.
