The Desk Job

&nbsp The Desk Job is an achievement/trophy in Deus Ex: Human Revolution. It is earned by convincing Wayne Haas to let you into the Detroit Police Station to get into the morgue

"You convinced Wayne Haas to let you into the morgue."

Overview
This achievement is a "conversation achievement". It is straightforward enough to get this achievement first time. Wayne Haas is an old squadmate of Jensen from his SWAT days, and has been suffering from guilt due to actions taken in the massacre. He blames Jensen for all his misfortune, especially that he is now just a 'desk sergeant'. You must somehow talk Wayne around into letting you into the station.

Stategy
Being sympathetic and nice is the best way to get through this section; you must convince Haas that he isn't to blame for the child being shot in the massacre. He will ask you to tell him outright that it isn't his fault. Once you've done that, he will back down and open the door for you. The achievement will unlock once this happens.
