Yes or to pressure you into confessing, honestly good interrogators can do this without the machinery.

Good carpenters can build stuff without nail guns, doesn’t mean it makes sense to use hammers.

Carpenters use hammers all the time…

Uh yeah… just like investigators use tools other than polygraphs.

The point is that just because something can be done without a specific tool does not mean you should never use the tool.

I guess I should’ve added “doesn’t mean it makes sense to use hammers exclusively" for the HN pedants.

No, because I would never talk to them.

Unless you just never talk to anyone, how can you be sure you'd know?
