Spear hunting was specifically outlawed in Saskatchewan when some ahole filmed a couple videos about killing bears over bait, hunting from treestands with a spear. Their skill was sorely lacking. It wasn't humane, and the producers seemed to be really proud about finally pinning a writhing bear to the ground with a spear though its guts. All game animals deserve a quick death, not stunts. If you're really competent with a spear, and it's legal, go for it. But make sure your skills are up to the task.
