Additionally, I would suggest removing the "Acquire Permissions Settings" from the 
"View" permission, and making the "View" permission only available to managers.

This is easy to do, assuming you called the DTMLMethod above "debug_request" and
created it in your Zope Site Root, then you could:

1. Navigate to http://mysite.com:8080/debug_request/manage_access
2. Scroll to the bottom of that long page.
3. Uncheck "Acquire Permissions Settings" next to the "View" Permission/
4. The "Manager" box should already be check, verify this.
5. Click the "Change" button near the bottom of the permission list.

Forgive me if I over-explain.
