I hope they were immediately released if you can’t get an indictment. The reason they couldn’t get an indictment is because the prosecutor didn’t really want one. Grand juries only really hear what the prosecutor wants to tell them. That’s why it’s said you can get an indictment on a ham sandwich. If the prosecutor just said “he shot her after an argument” with no exculpatory evidence he would’ve gotten an indictment and that would’ve been okay and cool with the US supreme Court.
