Boi, unlike the Hong Kong Police, the US police are usually overworked and underpaid. Most of the time they don't get paid overtime. Not to mention some of them are National Guard and US Army / NAVY reserves. Sure there are some lazy assholes but it's just a minority. A local precinct in such a neighborhood probably doesn't receive enough funding and the US gov Federal and states.....especially some states have been broke since the early 2000s. I wouldn't say they are lazy. They just don't give a damn. A different sort of fucked up mentality.
