It's a reference to this quote:

> New York State chief judge Sol Wachtler was famously quoted by Tom Wolfe in The Bonfire of the Vanities that "a grand jury would 'indict a ham sandwich,' if that's what you wanted.

Yes, I'm well aware. Indictment is in no way being found guilty by a jury of your peers though and has wildly different standards of evidence.

It's still a valid point, a prosecutor is the one presenting a case to a grand jury and has ample opportunity to tip the scales towards indictment or not. It's not like the accused have any similar opportunity to present their case to the grand jury, it's completely one-sided. Not saying there's anything wrong with that, but it's important to note that an indictment is not comparable to a case that's been tried in court.
