I’d expect that with the zillions of crime scene photographs taken, the need to use chalk to outline the body is lessened, and simultaneously, with more advanced forensic techniques, the danger that chalk would contaminate evidence is increased.
In modern crime dramas, I don’t recall seeing chalk outlines around bodies, but around other evidence like bullet casings, presumably because they might roll somewhere. If that’s true, then they’d still bring chalk along.
So would chalk dust. Are we sure this isn’t just a movie thing?
Chalk dust would just settle, any hair or dirt or otherwise from the aerosol could be moved pretty far away.
Also, dustless chalk is thing as well…
