This is a conspiracy against the United States and must be destroyed! RICO their butts, and use the Insurrection Law against them...
If they’re using rental equipment it is easily traced. Harder to trace but still doable if they have a sympathetic contractor or delivery service that owns their own equipment. Still, with the amount of surveillance equipment and recordings it wouldn’t take long to figure out who is who.
I expect a couple of good hackers and a years supply of Red Bull for them could get all the answers in a week.
Something that requires warrants and will hold up in court would take maybe 2-3 weeks.
Best bet would be to find out who is doing the deliveries, where they are buying from, who is paying and RICO the whole lot.
Time to go to work on these seditionists.
