To make it clear what I mean, imagine this hypothetical conversation: Supermarket: "We need a candy bar they we can sell to our customers" Hershey: "That is our core business. We will sell you candy. It may be recalled, if we discover problems." Supermarket: "Is a recall likely? Do you often recall candy? To your knowledge, are you currently selling bad candy?" FDA: "Yeah Hershey, is it likely? Are you currently making toxic candy?" Hershey: "We have a number of organisational and technical controls in place to prevent contaminated candy. We do not have a history of contamination, and to our knowledge we are not currently contaminating candy. Our controls have passed third-party audits." Supermarket: "OK, so to the best of your knowledge as candy experts, this candy you're selling me will be good to sell?" Hershey: "To the best of our knowledge, yes." If someone warns you about a possible eventuality, you simply don't pretend that the eventuality is impossible. That's why they warned you. Obviously nobody wants that. It's just plain ignorant to have a shocked Pikachu face when the thing they warned you might happen in extenuating circumstances happens.
