I remember this case.
The felony murder statute exists in most states. But, it is general not considered a death penalty offense, but second degree murder, the same as felony drunk driving that results in a death, even if the drunk driver did not intend to do harm, even if the drunk driver did not cause the fatal incident.
IIRC, it was critical that Wood intended to commit a crime to get the death penalty, or at least knew it was likely a crime would occur. The court ruled that whether or not Wood had any knowledge a crime would, or would be likely to, occur, he was guilty because he knew the shooter had a criminal record. I think the court accepted the defense argument that Wood may very well have been just giving a friend a ride, but ruled it was irrelevant.
If this argument was applied to cops in Texas...
