Black guys for the law enforcements, because extra variation is always good, especially on same-looking masked guys. And Chains are no longer represent black population as criminals.

Basic:
Replaces asian variant of murkies, blue swat rifleman, heavy-shotgunner and a pale version of white-shirt security guard (The pale version still in a game, as red-shirt variant).

Non-vanilla things:
Open-face blue swat rifleman head variant has been replaced with a masked black version.
The visor on the heavy Shotgunners are now raised up for a little bit of variety.
The masked FBI agent no longer uses the same facemap as the version with glasses (his thin lips were so obvious).

Fixed some texture issues:
Asian cop mustaches now actually connected.
Fixed visible eyes textures on the eyebrows on heavy-swats and bulldoser.
The arms skintones of the short-sleeved cops now match their heads.

Replaces unused axe_fire_df.texture & sledgehammer_df.texture.
Diesel Bunlde Modder Tool required for installation.

Facemap texture from Cinematic mod for HL2.
All edits made by me.
