They also boot anybody that knows the defendant, the circumstances, relatives, or that has issues with the supposed crime (like in abortion activists trials pro-lifers are booted so your jury is a jury of proaborts, similar with militia, gun rights, property rights) etc..
In short they've redefined peers to mean strangers with a predisposition to favor the states case.
Not actually, i've always been booted by the defense, prosecuters love me.
