I was listening to my local Public Radio station and they were interviewing an author about his latest crime novel. Blah, blah and more blah.
Regardless of the question asked, his central theme was that he made every effort to visit the actual locations he was writing about, talk to real people who did the jobs his characters did and basically just do some honest research to lend some credibility to the stories he wrote.
He gave a few examples of receiving letters/emails/tweets from his readers about some detail he got wrong about a particular building or whatever and then he chuckled and said...
"But nothing generates more critiques from my readers than when I get something wrong about guns."
We've all had great fun pointing out "movie mistakes" on all things firearm related and I thought it interesting that people would take the time to write this guy about incorrect gun info more than any other topic.
Although he didn't mention it outright, I could hear in his voice that he wasn't a gunny but knew he had to take a few trips to the range before writing his next book.
