Allow me to pull back the curtain on the news business: it's a profession populated by hard-working real people, who often invest their own money and vacation time to go to professional conferences and seminars to learn how to be great journalists. They study their craft. They aspire to write better, interview better, report better. It wouldn't occur to them to make up sources. They wouldn't lie in a story.
They wouldn't risk losing a job they invested years trying to get.
Are there unscrupulous people? Sure. Just as in any industry. But these people are one in a million. The majority are people just like you: would you lie in your job? Neither would a journalist. They go to work each day trying to do right, putting in an an honest day's work, doing a noble job.
To hurl blanket, generic accusations about making up sources or stories is insulting and offensive. And if you think this is just idealistic drivel, maybe it's because you don't want to know what's behind the curtain; if so, it doesn't change the fact that news people are honest professionals.
