Amnesties don't solve everything, so stop saying they do, because they don't.

To combat knife crime in my area, the police announced a knife amnesty. After a month, stabbing related deaths were down 40%, but choking on whole carrot related deaths shot up a whopping 1800%.
Evidently they haven't learned their lesson, because they've just announced a clampdown on drug use, which will entail a spoon amnesty. Now I have to move house so I can use a full set of cutlery without fear of imprisonment. Hell in a handcart.
