How I read the regs:
http://albertaregulations.ca/hunting...r-seasons.html
so there is an archery only season. There is also a "general" season where the limitations of my previous post would come into effect "no traps" etc.
I have to think if the spear hunter did anything illegal, he would have been charged by now. Furthermore, the guide camp who baited and put him on this bear would have altered the authorities what he was doing/had done or at the very least told him that this action is illegal.
