Never trust Democrat appointed commissions and committees.
They dance around the facts and alter the story to fit their pre-determined 'narrative.'
Not if they are taking a picture of the sign and the ship, then sending it via text to the sailor in question.
Think in terms of 21st century tech.
And
the lettering is too small to be seen from the ship - the sign would only be readable from a picture sent to the ship or when the sailor in question had disimbarked and was getting close to the sign holder.
