OT and silly...
But I sometimes wonder if lawyers and professional witnesses hang out together sometimes.
There was a trial in the 70's - a famous one - where the defense attorney was cross examining the lead detective in the case and the defense lawyer insinuated the detective was a liar, incompetent, dirty and on and on.
Turns out they were really, really good friends and jogged together every weekend and continued to do so all during the trial. They just left the trial and all it entailed in the courtroom.
