Not quite insider information. Someone has to gain something that isn't public knowledge. When you call a lawyer wo isn't directly involved, not only can you take his words as accurate, but he can't be held for inside information by simply fielding a call.
That I know for a fact. Good luck prosecuting that poor guy.
Would add you can only get in trouble in most all cases if you financially benefit from the information.
Remember anything can be side if it is in the 8K. That is public record and knowledge. So f some lawyer or anyone for that matter makes a comment relating to a closing, especially someone not on the inside who is guessing on things, is by far not inside info.
Not a securities lawyer, but have asked one before.
