Thumb drives cause terrorism (like guns cause killings). But we can reduce terrorism - by thumb-drive control - with regulations that take away the key device that terrorists use to promote killing. Raising taxes on thumb-drive sales could escalate the impact of this control.
Selling "thumbs-down" ribbons and bumper stickers will rally the supporters (- but you can expect some "sore-thumb" ideologues... to oppose it).
SHE: We need thumb-drive control to put a stop to terrorism
HE: I wonder if brain control is needed here..?
SHE: What does that have to do with terrorism - or guns?
