WASHINGTON -- What would the world look like without journalists?
That is the question the Newseum posed to passerby Monday.
Normally, the front pages of newspapers from across the country are displayed in a glass case outside the front of the museum.
But Monday, those pages were blacked out, in tribute to 21 journalists who lost their lives on the job in the last year.
One of the names added to the memorial wall this year is John McNamara.
He's one of the five people killed at the Capital Gazette last year.
Every year, the Newseum rededicates its Journalists Memorial in recognition of the "dangers in the profession of journalism and those who have died in pursuit of news and information."
This year's 21 names will be added to the current 2,323 professionals currently recognized on the memorial, which includes journalists dating back to 1837.
Each year, the Newseum selects a representative group of journalists whose names are added to the memorial.
"The memorial is rededicated annually to illustrate the ongoing dangers faced by journalists around the world," Newseum officials wrote in a release.
The Committee to Protect Journalists reported 54 journalists died in action in 2018, with confirmed motives. So far in 2019, five have been killed, according to the CPJ.
