he didn't die.... TVB changed the ending after pressure from the online community. go google and find out how the ending changed to accommodate the "revival" of laughing. and btw, in real life, police won't disclose the death of any undercover cop. the beneficiaries will still get compensation for death while on duty, but applications for burial in Gallant Garden will be rejected
lol i thought the NBC one was real, then I realized that everything on the page was photoshopped. hahah
