What if it helps clean up the homeless encampments and crime like Gavin Newsom did in San Francisco when Xi visited recently? That would be good!
D.C. is a dump and has been my entire life. There's been a drop in homicides since the peak in 2023, but last year was still 15% higher than in 2019: https://www.axios.com/local/washington-dc/2025/01/02/homicid.... In 2023, the homicide rate in D.C. was 39 per 100k people. This is only a little better than the civilian death rate in Iraq when it peaked in 2014 during ISIS (that was around 50 per 100k).
This is not a "guns" issue, it's a policing issue. Idaho has among the most guns of any state in the union, and Boise is as safe as a western European city, with 1/30th the homicide rate of D.C. Even several large U.S. cities, like Austin, El Paso, and Virginia Beach, have homicide rates 1/10th or less of D.C.: https://en.wikipedia.org/wiki/List_of_United_States_cities_b....
D.C. is a rich city surrounded by wealthy suburbs. There's no reason for it to be as unsafe as decaying post-industrial cities like Philadelphia or Baltimore.
