The spiral pattern the bomber took around the RNC and the DNC serves no purpose except in parading themselves across capitol police cameras.

The ideal route for the RNC would avoid ALL capitol police cameras. The ideal route for the DNC avoids all but one, and even that one could be avoided by NOT crossing the street.

Keep in mind these aren't just cameras!! There are Capitol Police officers stationed here. Some of these have 3 officers stationed!

People who intend to plant live explosives DO NOT parade themselves in front of LAW ENFORCEMENT CAMERAS!!! This person wanted to be on camera. They had an explosive with a phony detonator, and we can now say with certainty that they wanted to be seen but not identified.

Both at the DNC and the RNC, the bomber acts as if they are carrying a live explosive. However, that concern ends after they place the bomb. After they place the bomb at the DNC, and after they place the bomb at the RNC, the suspect begins wearing the backpack. They discontinue their concern over the backpack...and begin wearing it. That means two things.

1. There is only 1 bomb in the backpack at a time.
2. There is a pick-up location.

Number 2 especially makes sense given that, according to Kyle Seraphin, the bomber used the metro. The D.C. metro does random bag searches. Wearing a hoodie, a mask, glasses/sunglasses (watch the 1st note on cam 4400) through the metro while carrying a backpack away from your body like a bomb is a good way to go to jail.
