There are plenty of "reasons", some perhaps more valid than others, for the riots in Minneapolis and LA so far, but expected to reach many more cities. These are systemic problems only anecdotally related to "racism", which is a simplistic excuse, not a reason.
We haven't had equal justice at any level of the 'system' for several decades. Where are the criminal prosecutions for politicians raking millions off the top in scam after scam? Where are the jail terms for bankers whose companies have paid billions in fines...but no personal accountability? Where are the charges against the governors who have broken their own lockdown rules? What about the Coup attempt? Fast and furious? Even down to every day speeding tickets - no matter your evidence, the cop is always right. What about George Floyd? Choked to death wearing handcuffs, and no arrest.
Police from the peoples point of view: I know several great cops. But the bad ones destroy the entire institution of law enforcement because you don't know who you can trust. Comey at the top along with Brennan are great examples of ultra-corrupt lunatics. No charges. This type of thing goes on every day against hundreds if not thousands of regular Americans. State cops SWATing businesses for "not social distancing". Imagine! Local cops do the same thing - enforcing unconstitutional laws, crushing law abiding citizens with SWAT raids, threats of force and death. And people wonder why there are riots.
People from the Police point of view: Cops have to deal with dregs of society...people you have nightmares about. Cops keep them away from your door, for the most part. They risk their lives every day doing this, and it takes it's toll, not just on the cop but their families too. They do this under rules of engagement that severely limit their chance of survival - but they still do the job. The good ones deserve more that we can ever repay...the bad ones should get out and find something else to do before they lose it.
Judges and Prosecutors: these are the real source of the problem. The Prosecutor plea bargains felonies down to meaningless misdemeanors to get a guilty plea, or doesn't bring charges at all. The Judge, unless forced to, gives light sentences for violent crimes and let's everyone out of jail to prey on the public again. What a laugh they must have at our expense. It's no wonder that the good Police get pissed...arresting the same violent offenders at great risk to themselves only to see them on the street again faster than they can get the car turned around.
So, it's no wonder people are going mad. It's a mad, mad world. To coin a phrase: "No Justice, No Peace". It's true - but it goes for everyone. We the People, the Police, the Politicians, the Wall Street big shots. The same justice for everyone. Equal Justice Under the Law. Very little of this has to do with race. It is a human condition that affects us all, equally.
Our Institutions have been destroyed by corrupt Judges and Politicians. Equal Justice Under the Law is the way to rebuild them, if it's not too late.
