Ok, important question. Was the aircraft de-iced, within the allotted time frame? and if so/or not so, can this be verified? (Verification is a BIG issue here) It is an essential point to the entire argument, because depending on the result, should, under certain conditions, this be revised?
99% of us say we would not go with that on the wings (me included). But if it was de-iced, this surely raises serious issues about de-icing that perhaps have been previously overlooked.
