I doubt that any defendant would feel aggrieved because of a mistrial.

His victims might. The taxpayers might.

The taxpayers should demand that the legislature not pass and the prosecutors not prosecute unjust laws. As for victims, most of these cases do not involve actual victims -- that's why juries are disinclined to convict. And, of course, until the defendant is convicted, he has no victims because he is an innocent man until proven guilty.

This issue rarely comes up when you have a real victim of an actual crime.
