Personally, I would never follow a robber outside after a robbery, and I probably wouldn't shoot a robber if he appeared to be de-escalating by going for the door. I would probably try to find cover instead, if I hadn't already. Chasing after someone puts you at a tactical disadvantage. Following a robber outside after he exits a store puts you at serious risk of being perceived as the aggressor by bystanders, or by arriving police.
ETA: link to article http://www.ajc.com/news/nation-world...a-1286015.html
The article says that the off-duty NYPD officer and retired Nassau officer saw the ATF agent and the robber in a "skirmish" outside as they approached the store. It's easy to see how that could have gotten out of control.
