So I just watched the Fourth Season of the wire.
He's the Season's villain, right?
>betrayed Randy and basically led to his eventual death
>fucked up the murder investigation allowing Snoop and Chris to murder countless more people including Old Face Andre
>lied about a CI and stole Police property
>Jewish
>ended up working for the evil Jew lawyer after being dishonorably discharged for a general bad career
Herc turning out to be a bad guy after all is a testament to how mature The Wire was compared to an average TV show.
It would have been much easier to continue showing him as this goofball who's rough around the edges but ultimately means well, but instead they seized the opportunity to teach us a lesson that arrogance, ignorance and succumbing to your lowly instincts often enough can make you the bad guy even if declare yourself to be on the good side.
