I know English is evolving when I hear these words in a courtroom

I was recently snared into Jury Duty in Massachusetts.  This isn't so much an article about that.  Instead, this is about something I noticed while listening to the case before me and my 5 other jurors; word choices.

The first interesting word was uttered by the Prosecutor quoting the defendant who was fighting a DUI charge. The Prosecutor stated that the defendant pleaded with the arresting officer to cut him a break because he was not cocked.  This word cocked was used in a mocking manner by the prosecutor several times in his opening and closing arguments.

The second word that stood out was spoken by the Defense attorney.  While questioning the arresting officer, the Defense attorney asked about the likelihood of something-or-another.  What caught my attention is that he used the prolly, instead of prob'ly or probably.  The use of this word in such a formal manner struck me, since the word is still considered by many to be of the mythically inferior not-a-word status.

The last spoken element I picked up on was the Judge's use of the idiom begging-the-question.  I've written about the idiom begging-the-question quite recently.  There are two official definitions for the idiom.  The traditional definition is based on a logical fallacy.  The modern definition is an alternative for raises-the-question; this was Judge's use that day.  It is interesting to note that both definitions appear in dictionaries now.
