Reservoir Dogs members involved in a real-life robbery
A member of the Reservoir Dogs heist team who gets involved in a real-life heist has a few things to say about the movie's plot and the heist.

One of Reservoir Dogs' team members who got involved in things like real-life robberies had some issues with the film's accuracy. The themes established by Reservoir Dogs would continue to be addressed in Quentin Tarantino's follow-up films, as well as the tone of the rest of his work, which is mostly known for its high doses of gore and violence -- and Reservoir Dogs is all about jewel heists. The problem is, it has a lot of violence.
In Reservoir Dogs, crime boss Joe Cabot (Laurence Tierney) and his son Eddie "The Good Guy" Cabot (Chris Penn) assemble and lead a group of criminals with the aim of Steal thousands of dollars from a jewelry store. As the heist doesn't go as expected, the team members end up revealing their true colors after the fact--however, there's one guy who doesn't reveal much of himself. Mr. Blue (Edward Bunker) only makes a brief appearance in the opening scene of Reservoir Dogs and doesn't make it back to the safe house, but Bunker turns out to be the member of the team with the most interesting backstory.
Reservoir Dogs’ Mr. Blue Was A Real-Life Criminal

Edward Bunker had a traumatic childhood, and at 11 he was sent to juvenile detention for beating his father. At 17, he became San Quentin State's youngest inmate, but it was during that time that he decided to become a writer. However, he was eventually declared guilty of insanity after committing more crimes, including a planned robbery and a suicide attempt that feigned insanity. In the early '70s, Bunker was an associate of two members of the Charles Manson family (Sandra Good and Lynette Fromme) and operated a San Francisco drug trafficking. Bunker was arrested again, but thanks to the persuasion of influential friends and a lenient judge, instead of 20 years, he was sentenced to only 5 years.
While in prison, Bunker continued to write, publishing his first novel, No Beast So Fierce, in 1973, and since he now writes and acts for a living, he feels he can stop being a A criminal is gone. Bunker's first acting credits were in the adaptation of his first novel, Straight Time, followed by minor roles in various films including Runway Train and Animal Factory, and as Michael Mann Heat consultant. Because of his extensive criminal history, Bunker wasn't shy about pointing out how unlikely the Reservoir Dogs heist was, labeling the restaurant's opening scene as "ridiculous." Getting teams together and wearing the same clothes is never going to happen, Bunker explained, as if you're going to rob a place, you'll "want to be as unobtrusive as possible."
Bunker also adds that being given codenames and working with "someone as unreliable as Mr. Blonde" wouldn't happen, and that the restaurant waitress would recognize them after the robbery. However, he also admits that once he saw the film, he realized it wasn't supposed to be real, and from this experience with Tarantino, he learned to "be a little more relaxed in my conversations, Add something different".
What Happened To Edward Bunker After Reservoir Dogs

After Reservoir Dogs, Edward Bunker went on to appear in minor roles in several films, and, as mentioned above, he served as a consultant on Heat. Bunker also co-produced the short with director Sudz Sutherland, and wrote and directed the Molson Canadian Cold Shot commercial. Bunker also continued to write, publishing three more books, one of which Published posthumously in 2010. Bunker, who suffered from diabetes, underwent surgery to improve circulation in his legs and died in 2005. As for Mr. Blue, Reservoir Dogs doesn't say what happened to him, but Joe mentions that he was killed in a police ambush during the robbery. Blue's fate was played out in the 2006 Reservoir Dogs video game, where Blue hid in a movie theater until he was found and shot by the police.
