Well, there's nothing there that says she didn't. But she ALSO had solid evidence, most likely including video since Kat was at the Pentagon during the incident, of Oracle's team taking out a Mexican prison, on top of all the other allegations.
And canon is still canon. Max Lord had a longer and closer knit "Ties to the JLA" than Oracle did by far.
I think there's just a huge misread for some about this. Lois DID actually walk away. She took Babs' measure, was not frightened by Babs' empty threat, left a clear warning, and threw the fish back in the water.
It's our fault, DC's, I mean, because we really have fallen down on the job of showing Lois as a terrifyingly good investigative reporter. I always thought that we did the Luthor/Lois relationship wrong--I think he has all the power, and yet he still gets a little wee bit nervous when she walks in the room, because she is so unbelievably dangerous.
But we usually show her as a hostage. Greg Rucka did some cool stuff with her as a war reporter, but I still think we miss a bet when we don't have her as the reporter that CEOs and Senators and Mafia bosses would most hate to see show up at their doorway.
