If you lived in Kansas during the 1870's it would have been DODGE City: Possibly in CONTRARIAN Street.
a.) His means "his".
b.) Oswald's prints were on the long paper bag found on the 6th floor of the TSBD.
The bag matched the general description of the one Buell Frazier saw Oswald carry into the rear entrance to the TSBD.
The palm-print's position on the paper bag corresponds to the way Oswald carried it--according to Buell Frazier.
Now, who is avoiding evidence?
Touching a bag and thus leaving a print doesn't make that bag yours! If everything I touch and left a print on would be mine, I would be a rich man in no time! And why do you ignore that fact that the bag was made of TSBD materials and was found at the TSBD, allegedly on the 6th floor, where Oswald worked. He could have simply moved the bag and left his print on it, if that is indeed what happened.
Besides there also were other prints on the bag which were never identified, which leave wide open the possibility of others having held/touched the bag as well
Frazier was shown the 6th floor bag on Friday evening by the DPD and he denied it was the one he had seen Oswald carry. And, actually, the bag did not "match" Frazier's description at all. He said Oswald carried a thin flimsy sack like the ones you can get from a dime store.
