This was and is a disgraceful state of affairs, but it has been coming ever since Trump joined the Presidential election of 2016 and even more so since he became President.
The Republican Party has by degree or design allowed him enormous leeway and Trump is adept in using this to his advantage, in fact, believing that it amounts to acceptance of his actions.
In fact, in viewing some of the actions of the law enforcement at the US Capital building it may even be true that they are in agreement with Trump. This is especially so, when barriers were removed by some law officers, thereby offering even more encouragement to Trump’ mob.
This action by Trump and his supporters has been forecast for sometime and now it has come to fruition.
If the required actions are not taken against Trump and his supporters, then this can only get worse.
