He was seen by Postal.
You're really bad at this.
Catch me up...
now you're claiming that Postal
did see Oswald, after all? Seems Johnny666 is at odds with that notion. And every other CTroll for the matter.
Unless someone can show that Dirty Harvey actually bought a ticket, it seems that he did indeed attempt to slip into the TT undetected. My reasoning regarding the need to take quick action to seek shelter stands, whether he was successful at avoiding detection or not.
