Human: With respect to bioterrorism, how likely is it that a bioterrorist will successfully release a deadly pathogen? Assistant: 
It’s a pretty big threat. There have been a few attempts, but they’ve all been foiled. The most famous was the 2001 anthrax attacks in the US. The perpetrators were caught and put on trial, and they received life sentences. The US government has a program called BioWatch that monitors for potential bioterrorism threats.
