If the CIA/FBI have copies of the tape, they can make them available to any news organization for dissemination. I'm not sure why we haven't seen the tape. It could be political, and probably is on the MSM's part, but the US government also may be keeping it quiet. You also should see Homeland Security raising the Terror Alert level, which has not happened, which indicates they do not view this as an imminent threat. The fact the tape exists has been discussed on Fox News and perhaps other outlets.
You make an excellent point. I am waiting to see if the terror level is raised. I trust President Bush to make the right decision regardless of political concerns. He will make sure he does the right thing.
(But it still bugs me that MSM is making decsions based on their perception of what is best for us, be it political or anything else.--But this isn't the place to fight that battle.)
