First for those wanting more information on Ebola (EVD) before signing visit the Wiki entry as it is very extensive and well researched http://en.wikipedia.org/wiki/Ebola_virus_disease.
The following is my personal opinion and highlights from the research I have read, that I hope many citizens will share:
Based on the highly contagious and deadly nature of the virus, the fact there is currently no known cure Ebola, and symptoms may take an extended period to present pose a huge threat to large, especially highly concentrated populations. To bring infected persons, even under quarantine conditions is highly irresponsible. Any outbreak in US could bring much higher death tolls.
I understand there is much moral debate on this subject but to risk an entire populace for 2 people is lunacy
