Re-watching - Amazing fact
It's amazing more people don't love this show. Maybe is started 5-7 years later when social media took off maybe it would have.
Aside from the brilliant acting and story telling and realism, consider this:
For a show about about cops and drug dealers, no cops ever fire their weapons...except one. The only cop on the fire his weapon is Prez - in the squad room, at the towers, and killing another cop. NO other cop ever fires a gun.
That is realism. Despite all the talk of police shootings, most all go their entire careers without firing their weapon in the line of duty.
It is a subtle thing, but one of the little things that makes this show so great.
