I have slit the throat on many a deer over the years, two were road hit, one a well racked buck. The others were during my years of hunting in varying situations and more than one was racked, I worry more about the hooves, but if you approach from the back, they don't really play in. I have never had an issue getting a handle on a deer and putting it down quickly and quietly, regardless of where I was (even on neighboring property), where shooting it would have surely raised issues. It ain't that hard and yes, I always have a knife in my pocket capable of doing the job. It ain't that hard, you just need to get in the right position to control it's head and have a sharp blade. It is painless and takes a few seconds to expire.
