So if I fired a gun close to the head just to scare someone, and it blew their brains out, what would I be guilty of?
Manslaughter. You might well end up in proson for as long as you would for murder, but lacking the mens rea to kill someone, mean that it cannot be murder.
lacking the intent to kill perhaps. Though having an intent to scare/punish/even damage rather than just being careless or neglectful. Is there no distinction in law. A driver who carelessly doesn't look would be treated the same as a driver who wished to scare/punish?
