Ah I see, because everyone fails to depict something accurately that means it's meaningless to care that they display something inaccurately. Fuck off. If anything this manga would have been perfect set up for a joke where she uses her gun with a silencer, and is startled it makes such a loud noise. Her trying to do a stealth kill and startling herself with how loud the gunshot is making her socially anxious would have been hilarious.

It's implied that the only reason she got the train kill without everyone immediately looking at her is because of the silencer. My complaint about the silencer is fundamental to why that scene in particular is fundamentally flawed. It doesn't even matter thought because later the artist later contradicts himself by having the news report that the train killing could have been done by a "slasher". Implying it was a knife being used, which would actually be a believable alternative to the silencer shot.
Plenty of assassinations in history have taken place in daylight, plenty have been recorded. In story most of her kills have ironically been in daylight. Everything else in this manga doesn't bely misunderstanding as much as it is an intentional act of whimsy. The silencer making the gun perfectly silent is never explained or stated, it is taken as a given that a silencer makes a gun perfectly silent. In that case, it's obvious the author is relying on the audience's (flawed) understanding during the scene.

If my concern was proper vernacular I would switch to suppressor, however, we are in an informal setting, and an informal setting implies a change in language to informal colloquial terms. Everyone knows exactly what I am referring to when I say "silencer", there's no reason to change what word I am using unless it is fundamentally wrong, like the "clip" vs "magazine" issue.
Even then, the issue would occur because a "suppressor" may refer to a device that eliminates the muzzle flash as opposed to the noise a gun makes.
