I think Scots law would still clasify this as murder, either under common cause, or because firing guns in a public place towards shows a sufficient degree of wicked wrecklessness to establish the mens rea necessary for murder charges to be brought. Of course, their might have been some intervening legilslation in the 20 years (WHAT???) since I graduated.

The government recently floated their intention of introducing a new bill to narrow the definition of murder still further.
