What do people look at?
This is about the reason for, and consequences of, people not sharing it.
When people aren't sure what to do, they wait to see what others will do. If other people do nothing, they will also do nothing.
But are the other people doing nothing because it's the right thing to do, or because they were also waiting, or because they're just stupid?
If people don't share this as a result of learning about it, I believe the only way it will be used in the next 30 years is if I managed to convince the US government that it was important. I don't know if this is the case, but if it is, it's only because of several high-profile events that I believe were done by people who knew of this idea.
Simply put, if the US government does know of the idea and its role is important, then it means that people only used this idea because of crimes in which many people were killed. Would you be fine with that outcome?
If you would like other people to be able to summarize your response, take this poll:
