How about he wiped his prints? Ever considered that?
Oswald assassinates the POTUS, then takes the time to wipe his prints from the rifle, ditches it, then races down 4 floors and into the lunch room in 90 seconds? HAHAHAHA!!!
The bag is only "suspicious" in hindsight.
The bag was used to sheep-dip the patsy and link him to the crime.
There is no way he would have included a useless scope in the paper bag if he intended to use the iron sights instead.
Do you have some insight to Oswald's thinking that day? I haven't heard any such definitive statement on his thinking such as your "There is no way ... " comment.
I'm just using logic, which you LNers never seem to do. With LNers, it's all about denial, obfuscation and ad homs, which they somehow think advances their position. Fact is, the LNer position is untenable since they have no where to go when they run into a contradiction because it's all or nothing for a LNer. Either LHO was a lone nut or he wasn't. There is no in between. If only they allowed LHO to be part of a conspiracy then they could use logic to make their arguments instead of naively defending the WC and the LN narrative come hell or high water.
All it takes is 1 contradiction to sink the LN hypothesis, and there are dozens of them. The LNer response is to deny, obfuscate and/or insult, which is a losing debate strategy. And keep in mind, LNers are the fringe belief system here. Most of the world ascribes to a conspiracy and the vast majority are not CTs. It's just so damn obvious to those who apply logic and critical thinking.
