I guess it's illegal if someone or you happen to hit a deer and decide to mercy kill a deer.Im sorry but because of legal reasons please pardon the wording.
I may or may not have been in this situation before,where someone slammed a deer,crippled it[paralyzed from rear legs and one smashed front leg.I may or may not have mercy killed it because regardless of the law on the books it was the right thing to do..in my opinion of course.
When you are in an area with no cell phone signal...and a lady begging you to please end it's suffering..what would you do...? at night real late..no signal ,no -one else on the road?
I would do it again in those circumstances...that is if i did or did not do it...[:D]--[:)]
