Felony cases are routinely settled by plea bargaining, whereby the suspect pleads guilty in exchange for a promise of receiving a lower sentence.

Response posts should always add something new.  Responses that describe the post (i.e. "This is a great post.  I like the way you said....  Good job!) will not get many points.  Conversely, you might say "Whilst I agree with you on point x, I think...." or "You make a good point on y; what about situations where...? I believe..." Think of the response as way for you to further demonstrate TO ME your understanding of the topic.
