alt Hacker NewsI feel like you are missing the rather obvious or else the note implies. Luckily the law is not so rigid as to be hamstrung by such sophistry. I didn't assault you, I merely invited your face to make an acquaintance with my fist!
The reason the note works is banks don't want to pay the cost of having their employees getting their brains blown out. Passing a note with this understanding means one knows they are making a threat.
Agreed, and if this didn’t involve the threat of violence then imprisonment wouldn’t necessarily be justified—in other words, if this were the case, it would make sense to change the law to a purely monetary penalty. But of course it is an implicit threat!
