Accuracy + Fairness = Professionalism.
When in doubt, leave it out.
If you don't understand your material, your reader won't either.
Every statement in a news story or featuer must be backed up by evidence:

2. facts or figures
3. at least one illustration or example
Always make that extra phone call.
If you have covered all the bases in your research, the writing is just a matter of organizing it.
