[T. O'Heir]

A neck shot is not a reliable, humane, one shot kill. It's also a much smaller target. Keeping in mind that most commercial hunting rifles are not capable of those super small group's even on a good day.
"...a tracheal hit..." Is not as quick as destroying the lungs altogether. Suffocation is an extremely painful and slow death too.
People regularly survive neck shots and people are much easier to kill than any game animal.
