Bomber question

[Twigdodd]

Did the cops see the guy in the RV or someone else got out and walked away? Another words the remains were in the vehicle of the the guy being blamed on.
since the cops are walk down the other side of the street from the RV, cameras or cops should have recorded some thing?

 

[Citizen X]

From what I've read they did not inspect inside once hearing the message. They called the bomb squad and setup a perimeter.
