Memory Alpha said:Upon graduating from the Academy, Paris was assigned to the USS Exeter. His career in Starfleet was short-lived, however, and ended after he was involved in covering up his own piloting error which had led to the death of three fellow officers at Caldik Prime. Despite later telling the truth, he was discharged from Starfleet following the incident.
Memory Alpha said:One of Ro's early assignments was aboard the USS Wellington. During that assignment in the mid-2360s, Ro was a member of the disastrous away team mission to Garon II. During the mission, Ro disobeyed direct orders, causing the eight other members of the away team to die. Ro was court martialed for her actions and refused to speak in her defense.
Sorry, how are Paris' and Ro's backstories 'more redeemable' than Locaren's? He only caused the death of one person due to a bad choice. Bad call by the writers, but you can't win em all. Considering all the characters that reappear on DS9 from TNG, the penny-pinching thing couldn't have been a consideration. Unless they thought Voyager would be a flop and DS9 would make some money. Maybe they were right.
Also, the Doctor would have to have put a lot more thought into Paris' pseudonym in 'Author, Author'.
The problem is perhaps not with his bio from TNG, but the one the writers would create to make Locarno former Maquis. You couldn't strike out Paris' name and replace it with Locarno because, after a second time, he should be considered untrustworthy after he quit SF for the Maquis.
Of course, they could figure out some other way to make him the bad boy who needed a break.
