You’re involved in it if you have a direct effect on its outcome. Simple as that. Witnessing a crime doesn’t make you responsible for the crime. Being aware of a crime doesn’t make you responsible for it.

legally, you could be considered an accomplice. but i dont think we're talking on the legal side, more so the moral. i'll just say sure man, keep living your life not holding people accountable, don't say anything, just let it happen, you'll be fine, similar injustices couldn't happen to you right?
