I also noticed that when the tarp was put back on the men were not wearing gloves. Come on. Maybe it’s their van,eh? And anything we hear about found evidence will be what they make up to tell us. Just like the vegas massacre.
Same thing when they put the tarp on in the parking lot. No gloves, officers/agents leaning on the van with no regard to what they were leaving on the van.
Since they were watching this mail bomber, one might assume that they might consider the possibility that there were at least bomb materials in the van. As another pointed out earlier, they just loaded this thing devil-may-care and bounced on down the road.
That's an unusual protocol if you ask me...
