They still do. (I get the sarcasm, Ari) I was recently watching the activity at a small airport where the exit and the entrance to the terminals are adjacent. FFDO (on a DL RJ, yet ) walks up the exit lane, shows credentials, then passes on through. (At some level this makes sense, but at that level, screening anyone that has control of the aircraft does not.)
And to counter all the paranoia oozing from the original article, I feel so much safer now that the US pilot who discharged his weapon in an AirBus on short final has been reinstated by an arbitrator.
