This is horrifying! How may lives got "lost in translation"?

Pardon my ignorance, but isn't it a systematic failure of the Dept. of Education? English is very well defined language with precise structure and a lot of (not quite as trivial, to the contrary of popular belief) rules, it really gives an impression that our Ed. system doesn't have it's shirt together.

Also if we have communities so isolated in 2019 that language differs this much, how is it still not illegal to have court hearings without interpreters?
