How have courts interpreted the doctrine of concurrent intent in an attempted murder case?

As explained in People v. Bland (2002) 28 Cal.4th 313: "The conclusion that transferred intent does not apply to attempted murder still permits a person who shoots at a group of people to be punished for the actions towards everyone in the group even if that person primarily targeted only one of them." (Id. at p. 329.) Concurrent intent exists " 'when the nature and scope of the attack, while directed at a primary victim, are such that we can conclude the perpetrator intended to ensure harm to the primary victim by harming everyone in that victim's vicinity. For example, an assailant who places a bomb on a commercial airplane intending to harm a primary target on board ensures by this method of attack that all passengers will be killed. Similarly, consider a defendant who intends to kill A and, in order to ensure A's death, drives by a group consisting of A, B, and C, and attacks the group with automatic weapon fire or an explosive device devastating enough to kill everyone in the group. The defendant has intentionally created a "kill zone" to ensure the death of his primary victim, and the trier of fact may reasonably infer from the method employed an intent to kill others concurrent with the intent to kill the primary victim. . . . Where the means employed to commit the crime against a primary victim create a zone of harm around that victim, the factfinder can reasonably infer that the defendant intended that harm to all who are in the anticipated zone.' " (Id. at pp. 329-330.)
