I don't think the statement blamed the victim, but it's nevertheless true. I can think of two instances where alcohol caused drivers to make bad decisions. A driver some years ago couldn't discern which side of the road a parked police car was on, causing him to leave the road and hit two officers, killing one. He was found not guilty of vehicular homicide in this local case.
A second case I saw on a news program involved a man who had used alcohol moderately, had a migraine, parked, then decided he was able to drive. He thought he was still on an access road, but had actually entered a two-way highway and killed someone. He was convicted in Texas. The rationale being that the migraine caused the accident, but the alcohol caused him to misjudge his ability to drive.
Alcohol also obscures the taste of GHB and other "date rape" chemicals. It can lessen inhibitions making one more trusting in some cases. No matter what the victim had or did not have to drink, her killer is obviously a sub-human piece of garbage who, if found, should serve a life sentence. Of course if it was in Lauderdale County, he would get only 10 to 25 years.
