There have been protests throughout the United States since the death of American-American man George Floyd, who died after a police officer knelt on his neck.
That officer has been charged with third degree murder.
Jim Hanson is President of Security Studies Group and served in the US Army Special Forces.
He told Chris Lynch that Antifa and the radical left are to blame for many of the violent riots and lootings we have seen over the past few days.
He also agrees with President Trump who wants to designate the anti-fascism activists as a terrorist organisation .
