I mean, did you mistakenly type humane instead of inhumane here?
I'm not saying Kosher/Halal is humane, they are.
Because that would be surprising, coming from agricultural folk, who've surely heard of the methods rendering an animal unconscious first.
Well they say it is very fast.
As for rendering animals unconscious they also say at times the taser does not work the first time, therefore the animals will have to be tasered several more times to knock them out.
