A man gets on a Metro Bus on the 1600 block of Pennsylvania Ave in Washington DC. A passenger notices that he is CCing a gun in a holster on his belt under his sportscoat, and calls 911. By the time the bus driver is notified that he needs to secure the bus and prepare for LE response, he is making a stop on the 900 block of Pennsylvania Ave.
The MWAG is not an LEO, and is, in fact, carrying illegally.
Who has ultimate jurisdiction?
Which court will ultimately try his case, should it go to court?
Yes, this is sort of a trick question, but I'm interested to see how a CJ major would answer it...
