Especially not something a German corporation does.
The repair bills on my BMW are in contradiction to "delivering quality". The car instead appears to have been optimized for "delivering ongoing repair business" to the local dealership.
The modern German self-image is a lie.
Huh? The cartels are using primarily AR and AK pattern rifles smuggled through the US or stolen from the Mexican government.
Second, the weapons in question were sold to local Mexican governments.[2] The investigation appears to stem from the German government not trusting all elements of the Mexican government to use the weapons responsibly.
It was an attempt to dump thousands of rifles the German Army didn't want any more. Some subset of the rifles got in the hands of dirty Mexican cops and were either used by said cops in support of the cartels or stolen on behalf of them. The impact is minimal and HK is not supplying the drug cartels.
