"Politics is the Art of looking for Trouble, Finding it whether it exists or not, Diagnosing it Incorrectly, and applying the Wrong Remedy".
Sir Ernest Benn (1875 - 1954)
Biosafety Hazard Level 4 is the designation used for facilities that have sufficient safety measures in place to the worlds most deadly pathogens and chemical agents can be handled safely. Prior to Ebola there were very few of these. Andromeda Strain provides a good example of such a facility. They're not as complicated and elegant as a sci-fi movie but you get the idea. They are used in Germ Warfare development and vaccine development. Where the line between the two actually is gets blurry sometimes, for example, is the need to aerosolize Ebola for military or medical purposes?
