The Atlanta police should have thought outside the box. The Marta transit system was a smart move on the part of Nichols. And once Nichols got to Lenox Square, he could travel unnoticed in the "green" area between Lenox road and GA 400, behind a 20 foot wall that hid him from travelers on GA 400. I'm not sure he did travel via the GA 400 route, but it was a perfect route for him to take.
"The Atlanta police should have thought outside the box."
You are right, but acting on "How to I get to Lenox Square?" is not out of the box. They couldn't get the damned box open.
Haha...I'm sorry it's just funny to hear the words "MARTA" and "smart move" in the same sentence. It's quite a surprise that MARTA was so effective for a murderer, yet when I took it to Hartsfield Airport from North Springs (about a 25 minute drive) it took 2 hours!
