Pepper Spray is nasty... we had to use it on each other during training. Basically the second half of the day was a wash. All the trainees went back to the lodge and showered and then proceeded to take heavy doses of "painkillers" until the wee hours... I suggest single malt scotch, neat
... or perhaps with a piece of glacier ice, in the off-hand chance you are close to a glacier or an iceberg

I have done a fair bit of research into bears(for work) and I concur that this one seems overly aggressive, considering the fact that he followed the hikers down the trail. Of course, if it was an old, weak bear, perhaps he/she didn't want to give up what seemed to be a toothless, claw-less meal. Definite candidate for destruction...(or made into steaks... yum).
However, if any of you are interested in an intriguing book about black bears, pick up a copy of
Walking with Bears by Terry DeBruyn, PhD. (I love his last name... "of Bruin"). Black bears are very different evolutionarily than Grizzlies or Browns. Basically he conditioned a few females to accept him enough that he could walk into them on any given day (radio collar) and follow her around with her cubs to observe daily activity. One quick story from the book and then I will shut up. He once observed a female chase her cubs up a tree and hide under a bush. He couldn't figure out what was going on, and was getting bored with the bear when another human wandered by: a gentleman who promptly called out to another hiker, a woman, who followed the first hiker into the scene shortly afterward. These two hikers remained completely oblivious of both the author and the bear he was following, despite the fact they passed by very close (I can't remember the distance, but it was close). Anyway, after the hikers passed and continued on their way, the bear got up, called her cubs down and went about her business.
Not all bears are bad.... some are actually pretty cool.
Side note... Black bear charges are often bluffs.
Side side note... as predators move back closer to humans we need to relearn about removing and securing attractants in rural neighborhoods. This means bird feeders, compost bins, gardens, etc.
