I reported this crime to MPD's 50411 line this morning, by texting the photo by what little I observed.
Please note the brick near all the broken glass. It looks like the brick may have been at one time a law abiding sidewalk piece before it got loose and turned to a life of crime. Loose bricks that can be used to smash and grab are just one reason why I hate brick sidewalks. Oh, yes they are so pretty when they are first put in. But then life happens. Tree roots, soil density, flooding, and the odd utility crew who need to bust it up come by make it an uneven surface, where a brick can come loose and be used for evil.
I dislike them when there is snow and ice. It's that uneven surface again when manually shovelling, I can't go far before jamming the edge of my shovel into a brick that is slightly upturned. Which is why I'm thankful the sidewalk outside of my house is concrete.
Brick looks historic to present day people. However I can't find any proof that my street's sidewalk was ever brick. In 1880 my street was "unimproved" which hints that it probably had no real sidewalk at that time, considering how much thought the 21st century DC government gives to sidewalks compared to roads. The earliest photo I can find of my street is from the 40s which shows some pretty even concrete. I love my historically accurate concrete sidewalk.
