No, only defensive shootings are legal outside of war, so as long as their actions did not cross into assault style actions then there is no problem.
My issue is shooting into the back of a truck that is not evading you and not presenting a threat, that's an assault, not defensive. While we can draw some long string claiming it was defensive in the name of public safety, they were making no efforts for peaceful resolution when presented with no threat, made obvious by the shooting of two innocent vehicles .
Now while we can't be sure what happened at the cabin and if Dorner was trying to leave the cabin to surrender, if he was armed, etc.... the history of the LAPD's actions is not presenting a very good case for them. In an age of murky transparency, concealment under "personnel files ", and withholding info for legal purposes, we can only judge based on the history of it and some comments over a police scanner.

Latino news paper delivery woman and her daughter. Not sure of the other one.
LAPD was at the cabin? I thought it was DNR and local Sheriffs?
