See the U.K.

See the U.K. ban guns.

See Ebay.

See Ebay sell gun parts.

See the U.K. blame Ebay for their illegal gun problems.

I've got news for the U.K. Yes, Ebay does sell some assorted gun parts like barrels, scopes, triggers and whatnot. But Ebay does not sell guns, nor do they sell any of the serialized parts which are necessary to manufacture a gun.
