I remember the Newhall Incident,and like many other hard learned lessons,including the Miami shootout,it did cause much needed changes to be made in armament,training,and tactics. Something like this usually happens about every 20 to 25 years that has a tendency to quickly awaken the sleepers.
One civilian near the scene took one of the downed officer's revolvers and fired one shot at the perpetrators,probably single action,but missed.This incident took place during the beginning of what was to become a tumultuous era for law enforcement nationwide.
Although training and preparedness is so much better now than then,there have been many lives lost in the process of getting where we are today.
We must remember that even as law enforcement continues to improve,so does the criminal element.We can never train enough to be too far ahead of them.
Miami,Waco,Newhall,the Soledad Brothers,and all the way back to the OK Corral,has given us lessons that should not be forgotton, and the high profile gunfights of the past should always be part of the curriculum for police academy recruits,along with the politics of the era.
These are what brought us to the point where we are today,with current weapons and tactical training.Unfortunately,there will be more to be learned and to prepare for in the future.
