ADA requires most places to provide an interpreter to Deaf and HoH, even jails too, however interpreter availability can be issue if your court date is in morning, right after got arrested last night, so if you committed misdemeanor so you usually sent to home after stayed in jail for 2 hours, so impossible to find an interpreter in 2 hours.
I went to traffic court in 2012 for my speeding ticket and the judge told me about how HARD is find an interpreter so he decided to dismiss my charge without pay court fee, so eventually, I'm unable to drive due to Usher Syndrome.
It could be easier to say about don't commit a crime but people made stupid mistakes.
What about people who don't commit crimes are in prisons and jails? It's pretty common when a corrupt detective didn't do its job and put wrong people in jail. They should be able to access to translators, interpreters and videophones no matter what circumstances.
