If you go to 22nd and M with Street View, there’s a Walgreens on the corner. The CVS at 2240 M is in the middle of the block, on the other side of M towards 23rd. There is a light in front of it, but no crosswalk, and I believe the light is for the firehouse across the street, on the corner of M and 23rd.
M and 22nd are both one way, and the description makes sense if he was crossing M, facing the traffic on 22nd to his left, going towards the CVS to his right. The illegal left turn would have been a “left turn on red” from 22nd on to M which would seem like a right turn on red because of the one way. If this is correct, the car would have come at him head on, as he described.
The only discrepancy is that the CVS is not on the corner of 22nd and M, as would be implied by his phrase, “on 22nd and M”. This would have to be amended to “on M near 22nd” to be strictly correct, but I don’t think this is too much of a stretch.
Thank you. I haven’t been to DC since I was 3. ;)
