Why? Don't trust the seal, the latch, or the pressure relief? (other than those 3 items, I can't see any other possible issues)
Even Pelicans aren't perfect. I had my 1450 strapped to my deck, was shooting my tripmates going through Chittam downriver of me...and had a latch tab break in my hand when I put my camera in to run the rapid myself. If I'd have flipped, I'd have soaked my camera as the 2nd latch couldn't seal the case by itself.
