People say I’m guilty, he’s guilty etc but it’s unlikely to hear “they were found guilty” outside of jurisprudence, and to say that when referring to a judicial trial and then say you meant a lay term when the professional term exists is a bit lax.
I wouldn’t say “WiFi” in place of “internet” while referring to an IT problem for example.
This implies there’s such thing as a victim of genocide card which there isnt.
