The trick is that the charge is sufficient to penetrate clothing totaling 2 inches thick between the two barbs, not 2 inches per barb.

At 15 feet? From the manual:

"Be sure, however, not to fire at a subject who is over 15 feet or 4.5 meters away (measure 15 feet or 4.5 meters to see how far this is – it will probably be further than you think). If you do deploy at someone more than 15 feet or 4.5 meters away, the probes will not have sufficient TASER wire to reach the target"

From the video no one was within 15 feet, let alone close enough to penetrate a winter coat.

Using the ass end of the truck [~6 feet wide] as a measuring stick, it is clear that Agent Tree [Taser Guy] gets within fifteen feet - if not twelve feet as he leans in.
