I don't want to estimate. I want to have proof.

There is a lot of proof [supporting the U.S. case against Iraq] -- the proof of failure to allow inspectors in and failure to allow inspectors, once in, to conduct inspections in an unfettered manner.

It's tricky to say when something like this could jump from proof of concept to being out in the wild because a lot depends on what the author's motives are and whether he wants to send it far and wide or if he just wants to show how good he is. The spread of viruses also depends on what people do with their phones. If they are only making calls, it's unlikely they will get infected.

The proof is that we've continued to commission him and have a very good relationship with him.

I couldn't figure out any way I could win (the lawsuit). The burden of proof was with me and if they don't have my registration form, how can I prove I registered as a Democrat?

The proof of the pudding is that the Ford Explorer has seen virtually no decline in August.
