What's The Purpose of Police?

Article IV, Section 4 of the Constitution puts forth that a primary purpose of governance is to  "protect against invasion and against domestic violence."   In other words, we the people are to be provided a military service and a police force.
All in all, by and large and for the great most part,  police officers across America are among the bravest, biggest hearted,  best and brightest of all Americans.  They leave their homes every day, knowing that they might not get to return to those whom they love and whom love them.  They face actual existential threats from an ever increasingly psychotic and sociopathic society, hellbent on its own destruction.  They deal with a diverse myriad mix of races, religions, colors, creeds, genders, jack and jenny asses, and general jerks, as they objectively. apply and enforce the laws under the Constitutionally supreme Rule of Law.     
                                                                                                  

                                                                                    Dallas police officers console each other after the
                                                                                     shooting death of Officer Rogelio Santander.
                                                                                                  More US Police Officers Die on Duty
                                                                                                   Mostly from gunfire, vehicle crashes
                                                                                                   and conditions acquired 9/11/2001.

On the other hand, there is an infinitesimally small number who are hired through nepotism, giving us officers like Barney Fife.
.
 Some equally small number are just bullies, like the Minneapolis street cop, whose reaction may not be the sole, or even primary cause of death of drug addicted and influenced thug Floyd 
and my high school classmate who told another classmate and me, "I love being a sheriff's department jailer.  I get to beat the shit out of people without worrying about getting hit back."  I wish I had the picture of him dressed in full, authentic SS officer's uniform, giving the Heil Hitler salute, with his long hippy hair spilling out from under his military cap, as he taught a "Mini-Spectacular" special seminar on Hitler, Nazism and Third Reich Germany.
And a most minute minority are just uneducated, unintelligent, dumb mass Dummycraps.

I strongly advocate for much more education to complement police training, heavy on old school, pre- politically correct psychology, sociology, and anthropology, as well as organizational communications (COM 514) and communications in conflict management (COM 344), as taught to me by Professor Elliott Pood, PhD.  Because of the state of modern American society, contemporary cops  need classroom and laboratory experience above and beyond the current, typical A.A.S. curriculum in Criminal Justice or my own B.S. major in Law Enforcement Administration.  There must be more stringent evaluations of mental acuity and acumen, as well as emotional stability and balance.  Public policing is perhaps the most pressure inducing profession of all of the professions, trades and general jobs, particularly in these times when professional politicians constantly and consistently inject and insert politically correct politics into it.  With those higher standards of learning and presumed professional performance, I also advocate for higher pay for police officers; much higher.

With that said, let them do their sworn duty to be peace officers and not de facto tax collectors.  

I cannot and shall not ever advocate for limiting officers' abilities and alternatives in dealing with dangerous law breakers.  As their primary purpose is to protect the peaceable and law abiding populace from such criminals, I have to ask, how are they supposed to protect us, if they're not allowed to protect themselves?  Are they to be hampered, hamstrung and hung out to dry with the same type of repugnant and relinquishmentary rules of engagement that King Baracka Hussein O imposed upon our combat military forces?     

To close, I wish to state some simple statistics.  Police officers shoot and kill almost twice as many Caucasoids each year as they do Negroids.  Less than one-tenth of one percent of all Negroid homicides are committed by police officers.  If black lives really matter, let's concentrate on the killings of Negroid police officers and the dozens, scores, hundreds and thousands of black lives taken each year, mostly by other black lives in our Demoncat mismanaged metropolises.  

Yes, a google times, yes, black lives matter.  Blue lives matter. Jew lives matter.  Old lives matter. 

ALL lives matter!
