Vanessa Medina, a reporter for WSVN Miami/Fort Lauderdale, underwent some police training scenarios to experience what officers go thru specifically regarding when to use deadly force.  Vanessa admits she is gun shy and you can see instances where she mentally shuts down and stops thinking. Granted this is throwing a non-swimmer into the deep end of a virtual pool. While it is not real, the lesson does seem to come across. The last part is rather disturbing.
