Think about it this way: if a French tourist gets a severe toxinfection while eating in a seedy restaurant in some corner of the USA, would the French state, or even the family of the person, sue the US government for failing to enforce health codes / not having good enough health codes? Would you seriously imagine that trial happening and being successful?

Conversely, say the same person got equally badly sick while visiting a friend who works in a US government lab that researches and deals with live viruses. Wouldn't you feel the US government has a higher chance of losing a suit on this?
