The fact that you called it a 'lame excuse' suggests you must know Oswald would not want to 'look like a sniper'
No.
Try to follow along, please, if you can...
The person making the claim could not possibly know what Oswald was thinking, so any claim based on that alone would automatically be a lame excuse.
Get it now?
Of course you and your trollmates would think it a lame excuse. After all, both of you busybodies are here to protect the killer of JFK.
Tell us if the poster
claimed, or merely suggested that Oswald did or might want 'look like a sniper'.
I personally think it was an interesting take on the possibilities given Oswald's aforementioned BY antics, History diary, wanting to be remembered for the next 10,000 years...
Any hints in there for you, Martini?
