After being acquitted of all charges, the Socialist State will refuse to permit justice that contradicts their narrative, so the DOJ will file federal charges against Kyle. 

That will cause several things to happen. One of the biggest and first reactions will be public outrage - to which the Xiden regime has already demonstrated a suicidal indifference. So the DOJ will without question try to get Kyle on other charges. That will cause a political backlash which will further damage the regime's popularity. 

Maybe they will need to dig that trench to track the Xiden' regime's approval ratings. 

another thing that will inevitably happen is a crowd funding site will be started to make Kyle a millionaire. He will come out of this entire witch hunt a millionaire, so he will have some compensation for being  Kafkaesque martyr by being attacked by the full weight of a deeply corrupt political regime.
