Bioweapon research is illegal, many charge that the US is engaged in it

Robert Kadlec, Assistant Secretary of Health in Washington, denies that the US is involved with bioweapons research, as do most US officials. http://concerneduspatriots.com/pentagon-funded-mers-cov-sars-bioweapon-research/ 

Francis Boyle disagrees.  He says that the US has 13,000 scientists working in bioweapon research in a large number of labs. https://www.amazon.com/Biowarfare-Terrorism-Francis-Boyle-ebook/dp/B001FB6II6 

What is this if not bioweapon research:

Giving aerosol gain-of-function to pathogens is not bioweapons research?

Funding coronavirus/bat research in a level 4 lab is not bioweapon research?

How does this differ from bioweapon research:

Certainly, nonweapon rationales can be given for the research.  Nevertheless, creating a pathogen with aerosol transmission capability is to create a bioweapon.  

Is there any possibility of enforcing US law that prohibits the US from participating in bioweapons research and production?  Or do once again false “national security” claims take precedence over US law?
