Wisconsin man accused of shooting family's pet goat

A man in Wisconsin USA shot one of his family's pet goats when his wife refused to bring home beer. Yet Cannabis remains illegal while alcohol is legal nearly all over the western world, it bemuses me.
This story sounds particularly horrible for the goat too:

"After his wife arrived home, she and the daughter heard four gunshots and went outside and found one of the two goats with its entrails hanging out, authorities said. They said that goat had to be killed later by a sheriff's deputy."

What a horrible thing to happen and all because a man couldn't have his beer apparently, people really need think harder about what a burden alcohol really is on society and what can be done about it.
