1/7 Trump's speech actually opened quite well. He acknowledges the need for justice, called Floyd's death brutal. Things go off the rails after the phrase 'but we cannot allow'. Here the speech becomes about demonising all protesters as violent criminals 
2/ The bulk of his commentary shifts to demonising a non-specific group, shifting the focus of a fight for justice into a criminality trope of tackling 'criminals, looters, rioters'. He also says the'biggest victims' are peace-loving systems. This is unsubstantiated hyperbole
3/ His second section, rather than say focusing on a history of racist police brutality, is simply to try and 'evidence' the violence of non-specific crowds. He could choose to focus on peaceful acts of defiance, but the goal here is to make villains of anyone out in the street
4/ The next para involves a set of binaries (security not anarchy, healing not hatred). These create a simplified and binary worldview that eschew nuance and middle ground. Remember Trump's presidency is about polarisation and radicalisation - not consensus and middle ground
5/ The theme of his next paragraph is about escalation and power, not restoring harmony. He invokes the military, uses terms like 'dominate', threatens to override devolved democratic institutions for the sake of 'law and order'. Essentially this is classic autocratic spiel
6/ His final para is about giving the enemy a face, which is Antifa. Obviously there is no evidence that antifa is responsible for all of this, but this fits with the discourse of many Trump supporters and Trump himself, who prefers to see opposition to him as an organised entity
7/ The alternative is that he has to accept millions of people from multiple backgrounds oppose him. Finally, a quick corpus analysis of his speech. Law is mentioned 10 times, no doubt deliberately, as this speaks to people who do not realise law is not without prejudice
8/ So in short, Trump's speech is based around intimidation, rule by force on a pretext of law an order, smearing all protesters as violent, emphasising violence, highlighting disorder, and trying to find a scapegoat - an enemy within that justifies warlike methods - fin
