Yes, it raises potential questions that something fishy happened to the people who are passed out, however, sometimes it is unavoidable to do so. A good example is the guy in Santa Fortuna carrying Hector’s love letter to Andrea; if you want her to walk onto the balcony for her signature accident death, which I almost always do, you have to knock out the guard carrying it. Another one is loosening the wheel on Sierra’s car to cause a crash; you have to take a pit crew member’s suit to do so. However, in both cases, although there’s still a potential trace that someone knocked these guys out through uncommon means, there’s still the potential that nobody will realize that and that these guys just passed out from the stresses of their jobs, and the pit crewman in particular started to experience heat stroke and took off his uniform to cool off before he passed out. The alternative, knocking them out by hand and stuffing them into a container, makes it absolutely certain that somebody attacked them, and ruins the story of an accident having happened to the target, and will clue authorities in that somebody set it all up.
Almost every discrepancy with reality, outside of how accidental kills play out, can be explained in Hitman. How can 47 strangle someone so quickly, how can he break someone’s neck so easily, how can he choke someone out so carefully, how can he throw a wrench at someone’s head and knock them out non-lethally, how do his pistol suppressors shoot so quietly, how do poisons make the target die so swiftly?
As to those first four: his greater strength, unfailingly steady hands, and lifetime of practice, has allowed him to know the exact amount of force and pressure needed to accomplish these deeds successfully, that would not be possible in the real world. As to the other two, the ICA has designed and perfected suppressors and poisons to work better than they do in the real world, and ones found onsite that are not ICA brand are made by companies making such advances on their own.
This can be applied to the tranquilizer guns as well: they are specifically designed to work on adult humans of a general body mass, both swiftly and non-lethally. In-universe, 47 is either stopping for a moment to pull out the dart, or the dart is falling out on its own and those who find and wake up the npc just don’t notice it because they’re too focused on making sure the NPC is alright and don’t think to look for a tranquilizer dart. Problem solved, discrepancies neutralized, my parameters of perfection are intact.
