Parking Lot 9% 6%
Single Family Dwelling 6% 11%

I'm quite surprised that residences only seem to add up to 11% of homicide locations in 2017. Not sure if that includes/excludes things like murder/suicides.
If you root around in the data, for LA it is pretty clear that the homicide rate of non-bangers isn't that high.
