There is an old saying: Once is an accident, twice is a coincidence, three times is a pattern. Sometimes that saying needs to be adjusted depending on the circumstances. For example, one secret Chinese biolab on American soil is an accident; two secret Chinese biolabs on American soil are a national security risk.

One of these secret biolabs was discovered in Las Vegas, inside a home serving as an Airbnb. The lab caused several renters in the house to become “deathly ill,” and was littered with dead crickets. The garage, locked away from Airbnb renters, contained refrigerators with vials of currently unknown liquids.
