These are random drops within a prescribed area.....consistent with the DC Snipers. That would make me think that all the bomb sites were previously under surveillance.
If there IS a FedEx driver involved, the sites were all on his route.
The trip wire presents an interesting difference. He couldn't walk up to a door as in the others. So this one had the trip wire. But he MUST have been there before to know that and where and how he was going to set it up and leave the site quickly.
Victims....a car, person walking or bicyclists. Didn't matter. The bicyclists had the best chance of not being killed because they were in a small space...but on the move. So size is also a component.
I think the bicyclists may be a big help....especially as to whether this was or was not their usual route.
