I'm not sure whether anyone has spotted this or not, but I found a riot shield model in the game files. It would be really cool if someone was able to implement it in game; I know animations would be required, but where the model is still lying around in the files the animation very well could be as well, unless the idea was scrapped before animations were created. It's fully textured too, so players could mess around and create custom sheriff, NOOSE, SWAT, etc. textures for it which would be cool to see. I'm gonna look around and see if there are any riot shield-related animations anywhere to see if this could possibly make its way into the game. The model, by the way, is located in x64c\levels\gta5\props\lev_des\v_minigame.rpf and is called prop_riot_shield(+hidr.ytd/.ydr)

Yeah. I found that out a long while ago. Back when mod menus were still being cracked for GTA V on PS3.
