Although I (think I) speak/write English very well, it’a still not my native language and this specific article was extremely confusing for me, I don’t really understand what it means
“If you help someone commit a crime or try to commit a crime, such as by providing tools or assistance, you can be held responsible for that crime too.”
Yeah aiding and abetting is something like: your friend says “I’m going to kill the teacher” and you give him a weapon. You wouldn’t be the one killing the teacher, but you facilitated the crime substantially.
