Trump only uses police as props.
When his mob of violent militia assaulted the Capitol Police, he sat there and watched it on TV — and he NEVER met with those officers, or the families of fallen officers, afterward.
And today he stands with the J6 terrorists — NOT the police.
Trump may use cops as props, but pro-Trump sentiment is rife throughout police networks; many cops are eager and compliant props who probably consider those police officers who risked their lives, or lost their lives to fend off J6 insurrectionists to be traitors.
He only stands with them until it becomes a situation that might affect him personally. Then he will do what he always does, run. He's a loudmouthed coward.
