The second it happened, I didn't believe that a shrewd guy like Longmire would grab the knife that was in Connally due to fingerprint issues and especially since it was clear that Connally was trying to screw him. Now I'm having trouble with one of the Irish mob leaving fingerprints all over a syringe he used to kill a dealer. There are other implausible detail issues that the writers need to fix if they come back for another season - it's just lazy writing.
I disagree with your first point but agree with your second.
The circumstances with Walt were entirely different from the mob hit.
In the heat of the moment, people often act in ways that might be viewed as surprising. I think that very few people would have thought to protect their hand when removing the knife. Further, what is the point? It was Walt's knife which would have already had his fingerprints on it. One would also assume that Connelly's were there too (that is something that has not been explained and might be an example of sloppy writing).
I would however expect a mob hitman to be more careful but that could be explained by a sense of invulnerability. That would be consistent with what we saw when he was arrested and during the transport and escape.

When one has to make excuses for an implausible incident that's typically a sign that it truly is one.
Another one I just saw occurred after Katie shot wife-abuser TJ. He turns to her and points his gun at her and she just stands there for a long moment with her rifle aimed at him, before finally pulling the trigger. Unrealistic direction. She really would have shot him the second he pointed his gun at her again.
More excuses. In your case, on the off chance that you are ever in a situation where an extremely angry and threatening man has broken into your office and points a gun at you, I recommend that you don't shoot him and see how that works out. Darwin award winner. Have fun at the Ignoratorium.
You seem to forget that it was Walt's knife in the first place, so his prints, and even DNA, are already all over it. The guy was stabbing himself, Walt's first instinct, which would be the same for most people, is to grab the knife to try and stop him from killing himself. Who, really, is going to have the where-with-all in such a fast moving, hectic situation, to stop and think, "gee, I better not touch that knife, I don't want to leave prints on it"...? Besides, Walt didn't think he was doing anything wrong and wasn't worried about his fingerprints possibly incriminating him. Only criminals, while committing crimes, worry about their prints. You didn't think this through. This is just lazy criticism.
You're making lazy omissions of reality because of a childish, emotional connection to a television show. Another IMDB punk worthy of being sent to the land of Ignoratorium.
Funny how you purposefully dismiss her attack on me. Seems like you dismiss everything having to do with reality. Must be a Trump supporter. Have fun in Ignoratorium.
Lots of them. Q: What is the crime lab going to find on the gun Victoria pulled from the stream? Why would she go do that guy's bidding for him without stopping to think what other plans he might have hatched?
How could an experienced law enforcement officer be so gullible?
It wouldn't be a mystery crime drama if everybody did everything by the book, you have to have a plot and you have to have mistakes. Even the best running backs in the world will fumble every now and then.
