I would think at least two agents should be glued to his side at all times---photo ops be damned!
I agree with what many have posted here, I am soooo very happy that W is our President and so very proud of him (and don't think many others, such as sKerry and Klintoon would have done this). I want him and his family and team to be safe (and keep that in my prayers daily).
This appears to be a Big Time screw-up, the SS is always right next to the Pres (except during formal photos, speeches, dinners, where they're always very close by). I don't get this and, while I don't want to read too much into it, I sure hope it wasn't a 'trial run' as some have mentioned. I heard on the news he's going to Europe soon - -any issues and protocol need to get corrected NOW!
