Alongside the taxis waiting outside Union Station in Washington DC, the sight of uniformed troops standing next to armoured military vehicles has been greeting passengers getting off their trains.
It is a striking symbol of President Trump's efforts to tackle a "crime emergency" in the US capital, which has seen his administration take over its police department and send National Guard troops, FBI and ICE agents on to the streets.
Trump says his crime crackdown, which began on 11 August, has had an immediate effect: "The numbers are down like we wouldn't believe, but we believe it".
And he has claimed that it has led to an extended period of time without any murders, a trend he says has not been seen in the city US in decades.
So what do the crime figures show?
