Anons, DC commuter anon here.
Can confirm larger police presence than normal. Slightly concerned about this, given Qs warnings about false flags. Ive carried a compression bandage and celox powder (coagulating agent) and really hoping I don't need it.
Confirmed large increase yesterday of Amtrak special police at Union, some armed with ARs (long guns are the least common to see), most have leg holster side arms. Today, more police posted at metro stations, also with long guns; same continues at Union.
They've got Intel on something brewing I would assume – too early for the start of holiday travel.
