Nobody measured Hahneman or Cooper in shoes...
they went by height and not with or without shoes...neither were barefoot I can assure you of that...the bottom line is the FBI put him at 5' 8"...you have to find actual proof it's wrong...perhaps doesn't do it...
yes, apparently the FBI did measure his height with shoes on..he has a record and the height is registered with mugshots, especially if you do prison time...
You have incorporated poor assumptions into your logic.. and jumped to a bogus conclusion. You are, of course entitled to it.
I'll make this real simple..
Cooper was wearing shoes.. witnesses claimed he was "about" 5' 10"
Hahneman was wearing shoes. witnesses claimed he was "perhaps" 5' 10"
A typical rounded/truncated passport height of 5' 8" plus shoes is "about" 5' 10"
When people get their height measured that is without shoes, the 5' 8" FBI number likely came from his passport (not his prison record) that doesn't include shoes and the passport is rounded/truncated, no fractions.
So, it is typical for a passport number to be 1-2 inches less than in shoes.
Both the witness statements for Hahneman at 5' 10" and a passport reading 5' 8" can be correct.. that is your error. Conflating the context,
they are not incompatible when you acknowledge their context.
You assume that 5' 8" is his actual height in shoes. Both my passport and DL read 5' 8" but I am 5' 10 1/4" in dress shoes.. I checked. The 5' 8" is rounded down and my shoes add 1.5"...
and I have searched for his prison record, it isn't there.
