Men who violated the Navigation Acts, after 1764, were not tried in a regular court. Instead they were tried in Admiralty courts. In these courts, violators were presumed to be guilty and did not have a jury to hear the case.
Prior to 1764, the people who violated these laws did get to have a jury trial and were presumed innocent. When the laws changed, the colonists argued that the men had a right to have a jury trial. They argued that their basic rights were being taken away without a trial by jury.
Grover tells Percy that, when the Furies found them on the bus, they were asking, "where is it?" rather than "where is he?" It seems they are looking for an object, rather than a human.
