How many times have I flown around Liberty on my "undercover" infected character... No one has ever tried to figure him out, though I've always left plenty of hints that, with due diligence, would have revealed him immediately, trivially stopping him even for a routine check.
I partly agree with the author that too much power has been thrown at the infected, but the main problem is that no one even tries to do anything about them, or at least reveal them. Although sometimes it's worth just scanning and maybe something interesting will turn up?
There's something to be said for the origin of the infected, too. There are different factions (at least Aoi Isejin, Das Wylde, and D9 are not active nowadays) of the infected. When the Vagrant-infectees do their research, surveillance, and information gathering, the K'Hara, in turn, destroy people by affecting them. Not every Wild follows the goals of capturing, infecting the higher echelons of government
Yes, and in fact, these days the Wilds have absolutely no effect on anything. No one tries to infiltrate the government, and in the Navy and elsewhere there are sporadic cases, and it makes no sense.
upd: Oh, and also, we have plenty of factions that do surveillance on people... Even the LSF, as an example.
