The key word here is high frequency. There is a phenomenon know as the
skin-effect. It refers to the tendency of high frequency signals to travel
along the surface of a conductor. This will cause HF current to pass along
the surface of your skin and not through the body. A properly tuned
tesla coil is a high frequency generator.

A jacobs ladder is NOT a high frequency device. It operates at 60hz.

Another point: It takes very little current to kill a person. As little
as 0.1 milli-amps of current passing through the body is lethal. 
12kv is plenty to develop this much current if you were to grab the 
posts of a jacobs ladder while it is energized.
