ISP superintendent provides update on Delphi double murder investigation
Why not just say I'm 100% convinced or why not just say I'm convinced? Why say 110%? Did ISP Carter look at the sign-in sheet before coming out to talk? Did other LE present confirm someone being there? Why say he could be in this room? That one really got the hairs on the back of my neck standing and I was thousands of miles away. Saying you're 100% sure of something is enough to convey certainty to whom you're addressing that your word is true. What then is saying you're 110% convinced that something is so? Eyeballing the killer as you speak?
I'm really starting to think on this differently. I think ISP Carter is a very no-nonsense and professional man. I don't think he embellishes. I don't think he's theatrical or a drama queen. JMO
