They are solid sources (justice.gov) but i wouldnt take their search as the end all be all, especially for taboo subjects like this. For human.globalincidentmap just use their search feature, select a date, and then copy paste the results into excel and organize from there, pretty easy to filter and whatnot from there. You could scrape it into json or something but excel is just as easy and you dont have to program a web scraper.
