The doors of perception - proof oswald is not guilty

[Gordon Gray]

Just eyeballing it without actual measurements, it would seem that the distance covered by a shooter from the 6th floor window down 4 flights of stars, is greater than the distance Baker covered from were he parked his motor cycle, up one flight of stairs, to the second floor lunch room. And we know from film clips that Baker was sprinting to the TSBD door. Hard to believe it took him all of 90 seconds to get to the second floor. More like 60 -70 IMO.
