If it is "Top Secret", then somebody needs to go to prison for divulging the project. I suspect it is more likely simply a project in a high level biohazard lab. If they keep it wrapped up, it shouldn't be a problem. There's lots of virulent pathogens locked up in similar labs.
Funny you should mention that. Our local TV newstation in Little Rock mentioned last night that Arkansas was in the running as a possible sight for a location to build a new $400mm+ bio-terrorism laboratory.
