Human Looter

The human looters are a pair of thieves that are encountered by Shepard during the mission, Dossier: The Professor.

Overview
Around the corner from the clinic of Mordin Solus is an apartment that is being looted by two humans. When Shepard meets them, the looters argue that they were there first. Shepard is presented with several options here. Shepard can ignore the situation completely and ask about the professor, use Charm or Intimidate to convince them to stop looting, or kill them.

Tactics
There really is no right way to kill these two. They have no shields, or armor. Ironically, they don't even have a health bar. One shot is all it takes to kill the human looters.
