The biolabs in Ukraine are real and anyone in fedgov that says otherwise is a liar. But, biolabs are everywhere. Research is not a crime.

In my professional career, it was sufficient to know that there were lines not to cross. There are speed bumps so to speak that serve as check points where things like professional competence, facility infrastructure and justification come into play. I purposely structured my work to not hit a speed bump and equipped the lab with procedures and equipment to protect ourselves and others if we stumbled into anything extraordinary from the wild in the course of the work.
