There are plenty of cities w/ more crime than DC. I don't see it near the top of any of the most dangerous city rankings. See example: https://www.newsweek.com/map-cities-homicide-rates-crime-2112196.
Also, what are the troops really going to do to fight crime? You gonna send them in on a drug bust or to arrest anybody whatsoever? Give me a break. They're gonna just stand there and look tough like they did in LA. This is all show, again, and another waste of taxpayer dollars.
