"But now they're saying it was just a 'backpack'...!!"
When the cops detonated it, if they got a secondary explosion, that would show it was, in fact a bomb. Without the secondary explosion, it probably wasn't a bomb.
I am almost sure when I was reading the first reports they said there was A SECONDARY explosion. Now they are just saying the bomb squad detonated something to see if it contained a bomb.
The media sucks. They either get it wrong when they first report, like death toll will reach 10,000 after Katrina, or they try to cover up the truth that is first reported, (Drudge) like Clinton gets BJ from Monika Lewinsky.
I am thankful we have FreeRepublic with on the scene reports. Keep us posted on what you find out and let us know when you have pictures.
