I think the primary distinction is that a weapon in a criminal context is typically something that is used to threaten/coerce someone, or to enable you to cause (more/more severe) physical harm/incapacitation in a physical altercation.

Date rape aren’t used to threaten/coerce people, and whilst they can cause harm, it is generally not the intended goal when someone uses them.

So whilst I agree that classifying date rape drugs as weapons is a good move, there definitely are relevant distinctions as to why drugs are typically not considered weapons.

“They’re extradonarily narrow” whilst literally talking about an apple patent that covers ANY type of digital display device whatsoever that has rounded corners.

That’s not even close to “extremely narrow” in scope.

Extremely narrow in scope would be defining a certain radius of curvature (within a small +/- range), in combination with an aspect ratio (again, with a small +/- margin) and for a specific class of screen.

That would be an adequately and acceptably narrow design patent.
