The Law Enforcement Memorial site in Carson City is a little tricky to find. I didn't use the lat/long - I was looking for the intersection of 2nd Street and South Fall Street, but Fall Street never intersects with 2nd - there are sections of Fall Street well south and north, however.
The memorial is on the front grounds of the Nevada Supreme Court building - between that building and the main drag - Highway 395 through downtown Carson. I parked on the Stewart Street side of the Supreme Court and walked in, but you could park on 2nd Street across 395 from the Capital grounds and cross the street. There is no parking on the 395 side of the Capital/Supreme Court complex.
