a friend of mine(ex military) tried to sell me a book he wrote for 24.00 once(he made a fortune),,,"how to survive a chemical/biological attack",,, i told him no thanks,he said why,i said "you know thats not what will happen",,,he knew i was right we were trained at the same source but years apart.
that is,if the city you live in receives for instance a bio attack,the u.s. mil. will surround that city,go house to house and remove all of it's people. they will have the orders to enter every house,structure,shelter,bunker ect. and remove all living and all mortality's. then all will be examined,any with systems/test+ will go straight to one facility,all with none/test- to another separating children parents ect. that is if you are infected and any one of you leave that city on a plane,car,hiking in the woods you will carry the infection elsewhere and they know it and it will not take place.
remember at the beginning of the war on terror when the nut sent chem. weapons to the wh. house,remember it contaminated the machines at the post office ect.?,,,that is it will also travel via a host both living and objects. so they will treat it a little different camp-A this direction,camp-B the other,ect. and all the canned spam,m.r.e.'s plastic on the windows with duct take will be all burned at the same time.,,,,put your self in their shoes and you'll see the reason.
let's say the lights go off and they are not restored in 30 days. lets say you have 6 months supply of food and water. darkness will fall when you run out of gas for your generator,everyone who heard your generator and saw your lights will know you kept your food preserved while theirs spoiled. they will then eat everything in their house and drink all of their water,and then when their babies begin to cry they will look for those who are "not loosing weight and have energy",,,and they will realize if they wait to long they will not be able to take your food and water because they will be malnourished and dehydrated. and they will go house to house searching for the weakest ones first and when they come to the strongest they will watch and count the men till they narrow the count down and come with more than there are in your house.
first and foremost is water it will be the first thing you run out of. if you live in any city large or small with "city water",then you will realize you do not have a water well anywhere close to where you live because they passed laws prohibiting them years ago. now as long as they can the gov. will have them leave it on as long as they can but only a few hours a day and you will then be faced with the fact you cannot grow food. where would you grow it anyhow on the patio at your apartment?
here is a question for the "preppers",,,you had 6 months supply your last inventory of food/h20 showed you have 46 days remaining. how many more days can you remain barricaded in your home?,,,,,,,,,,answer,,,those who were not prepared ran out of food and water weeks ago and you are about to become "the sitting duck",,,,,,that is you should have left the stuff and gone feral several weeks ago.
