I have lived near DC since 2016, and in that time that city has fallen into pretty much utter chaos (and has been on a rapid decline since June 2020).
The volume of crime and the locations where crime is occurring have both increased/spread.
You and your car are both targets.
Underaged kids are being used in higher volume to commit serious crimes (e.g. carjackings, which can easily devolve into shootings/murder) because their records are sealed and the DC court system releases them from jail at 18.
When I used to go into DC more regularly,
I recognized the importance of being vigilant.
Now, with increased crime, including stabbings and shootings, and cops nowhere to be found,
I recognize that I am taking a personal risk anytime I enter the District.
While I am still willing to go, at certain times and for certain reasons, there is no way my wife is going to just meander in there with the children anymore, let alone be on the streets of DC alone at 4:00 AM.
Even mid-day, taking the kids, think of how exposed she is to a carjacker, while she is fiddling with car seats, etc.
Four years ago, I had little problem if my wife and kids walked a few blocks in Manhattan, even at night. They were together, and they knew where they were going.
That is over. Probably forever. While the “new decline” of US cities began several years back, Covid was the death knell, and there is no appearance of any type of restoration on the horizon.
I am too old and I have learned too much and my family is too important to me to just say, “be diligent” and pray for the best.
