The situation in the USA highlights that criminal elements will take advantage of any situation.
Instead of demonstrating the 'mob' resorted to mayhem on other innocents; businesses etc.
BUT, in the USA do you not have a constitution that says every citizen has the right to carry arms and defend oneself? Is this not the message Trump has been bleating out over his election campaign and presidency? So when black and ethnic minorities are murdered by the very people that are there to PROTECT AND SERVE them, have they no right to carry arms and defend themselves?
Four hundred years of slavery and racism, too many years of 'Martin Luther King' dreaming of a better life, or giving the knee to the national [laughable] anthem, enough is enough and if it is OK for Trump to say white supremacists can uphold their 'constitutional rights' against Governors and the covoid-19 lockdown, carry arms and all, then violence may be needed for proper and permanent change. Long live the Second Amendment.
Then again, it is a failed experiment, this United States of White America, so I am once more not holding my breath.
