[Arkham Knight] Why hasn't someone called the National Guard?

Seriously, have you guys seen what's going on down there? These random mercs have pretty much taken control of the whole city! I'm pretty sure I overheard one guy say something about how he "wishes they would bring in the National Guard," so why don't they just do it?! I mean seriously...the fear gas cloud?! How is one man in a batsuit supposed to handle that on his own?

Ugh. I'm voting for someone else in the next election.

They have, but the entire incident takes place over a few hours, and it'll take a while before they're ready to enter Gotham. You don't want to just rush into a fight with a large, well organized, well equipped force, especially one that is sitting atop an unknown chemical WMD.
