(written from a Production point of view)
David Weddle is a writer of several Star Trek: Deep Space Nine episodes. In all of the episodes he was involved in, he always wrote with Bradley Thompson. He also wrote the Star Trek: Section 31 DS9 novel Abyss.
"Inquisition" is his favorite episode of those he and Thompson wrote and considers it to also be their best.
Weddle is a great fan of legendary director Sam Peckinpah. He was a friend of the Peckinpah family and met the famous director many times. He later wrote the biography If They Move . . . Kill 'Em!: The Life and Times of Sam Peckinpah, which was published in 1994. Ira Steven Behr, a great fan of Peckinpah, read the book and arranged to meet Weddle, securing him a place on the writing staff with Weddle "being a shameless opportunist", as he himself admitted, making use of the opportunity to secure a place for his friend Thompson as well. 
Weddle has appeared in many documentaries about Sam Peckinpah. These include Sam Peckinpah: Man of Iron, Sam Peckinpah's West: Legacy of a Hollywood Renegade, A Simple Adventure Story: Sam Peckinpah, Mexico and The Wild Bunch, and Passion & Poetry: The Ballad of Sam Peckinpah. Weddle recorded audio commentaries for the movies in the Sam Peckinpah's Legendary Westerns Collection DVD.
Upon conclusion of the series, Weddle, together with partner Thompson, joined former Deep Space Nine colleague Ronald D. Moore as writer, executive story editor and co-producer on the latter's re-imagined Battlestar Galactica franchise.
Weddle has also written episodes for the later television series CSI: Crime Scene Investigation, Falling Skies, Defiance and The Strain, invariably in conjunction with partner Weddle. Their collaboration on Defiance reunited the pair again with former Deep Space Nine production staffers Gary Hutzel and Doug Drexler, who incidentally, had also worked as production regulars on Battlestar Galactica.
