Honestly, the fact it was stolen inside a government building in Washington, DC makes me even more suspicious. You had some sort of evidence on that phone that someone else did not want to see.
That would make for an interesting story for sure.
The reality isn't so glamorous. The phone was stolen because I left it inside of a restroom stall. The particular restroom was one that's very secluded. Most people there didn't know about it, to the extent that, the only people I saw there with any regualrity were the janitors whose job was to routinely clean the place. Not sure what else to say besides that what you're suggesting is extremely unlikely.
