Burn them.
Wasting is against German efficiency. Recycling might yield $2000 or more for this lot depending on how many there actually are. Use the money for something symbolic. Like night sticks for the police plus the permission to actually use them on aggressive Muslim mob.
“Burn them.”
That’s what I would do, but I can see why Germany, in particular, wouldn’t want to do that.
But what “desert” are they talking about? maybe we can take them and stash them in Yucca mountain.
