So consider this. Would you have gotten involved? (There's a really interesting backstory to this)

These discussions are highly fact specific, but when you look at the outcome of police involved shootings, it appears that there is not much risk.
You would have to find a jury that thinks it's more reasonable to let an armed robber go free, than for a properly licensed gun owner to use a specific legal right granted to him by law.
Along these lines, consider the McIver case in Atlanta, where the lawyer is being charged with the equivalent of negligent homicide for "accidentally" shooting his wife in the back while she was in the front seat of the SUV. It will be interesting to see how this plays out as far as negligent use of a firearm, if for no other reason than that McIver is being defended by some high powered legal talent, and not an overworked public defender.
