"When Council member Janeese Lewis George asked Geldart how he tracks the success of the D.C. police, he referred to the impact made by a specific tactical operation to target and remove a neighborhood crew in Congress Heights.

“On MLK and Malcolm X right there where, you know, we did 13 arrests in like two days, we saw 60% reduction in violent crime that stayed for three months. We’re still seeing a reduction of 60%. That’s the metric; that’s what I’m looking at,” Geldart said.

A shooting near that intersection last July took the life of 6-year-old Nyiah Courtney."

So no, some amount of crime will always exist. However, removing known violent criminals from communities can make those communities safer.

We need to offer robust community services that provide opportunities for at-risk people, support services for society at large, and hold people accountable for gun crimes and violent crime for the sake of the rest of the community. Letting repeat offenders continue to inflict trauma on the rest of their community does nobody good.

No need. Crime isn't really happening in DC these days.
