If you are writing a letter to the editor you need to be careful about what type of information you write in it.

Be careful about whatever you submit because what runs in the op-ed pages generally, in my opinion, carries more weight than what runs on the news side. What people pick up from the op-ed pages carries more weight than what they read in the news. You don't want to run something that appears, that you think is really strong, but then someone within your organization has a problem with it, or maybe some statement that you're making on behalf of someone in your organization through this letter differs from another opinion within your organization. You want to avoid those sorts of political problems that can happen. You want to make sure everybody's on board with the message that you're trying to get across.
