It's a trick, and it shows his inexperience at this level of a case. It is another form of a lie, not unlike his "lying by omission" concept, whereby if you repeat a phrase often enough it will subconsciously sink into the observer as a truth. It is how his client works (look at how many discussions still go on around here about Zanny) JB operates the same way. It is a good trick to use to sway a jury, not unlike Johnny Cochrains infamous "if the glove don't fit" mnemonic. BUT IT DOES NOT WORK WHEN YOUR ENTIRE AUDIENCE IS A SINGLE SKILLED OBSERVER. ie HHJP.
JB is continuing to argue motions hearings as if he is in front of the jury instead of in front of the judge.
