That's a very important question to dissect a bit.
When we collect any piece of intelligence, we are trying to build a picture, so every piece of intelligence is assessed on its own merit. In some cases, we will have a very solid source that we receive that information from, and in some cases we may not. We try to corroborate that information in order to build a better picture. Every piece of intelligence goes into understanding what the actual situation is, but sometimes you are still trying to build the picture, and you don't have a lot of really strong.... Our threshold in the service is to suspect that there's a threat, which allows us to investigate, so it could even be that we suspect this could be what's happening but we don't yet have that clarification to believe it.
