there's a reason the words "with prejudice" are present in the motion for mistrial that the defense filed.

If it is "merely" declared a mistrial, it'd go down as you say.

But, if it is declared "with prejudice", then they literally cannot charge Kyle with the same crimes from the same event.

Sure, they'll near-certainly shop around for a libtard "judge" to put Kyle on trial for a different litany of "crimes" from the same event, but that's a whole fuck-load harder than just repeat charging him with the exact same spurious bullshit.
