Good question David.

IF we truly believe in the Constitution, shouldn't we also believe it's for Everyone ??

IMO,
NO. However that also means that we cannot break our own constitution.

they have prisoners in Gitmo that have NEVER been accused of a crime.

Thats because many were captured as (POWs) they don't get court . After the war they just get sent back home.

The terrorist however some where charged and got court dates , some others are still waiting due to evidence gathering ? ? why so long ?

Riddle me this; Congress has voted for (War on Terror)
So technically a terrorist can be held as a (POW) with no court , the US instead sends them to court. IMO this is because if someone could prove that the War on Terror is over - the US would now have to send all them terrorist home.
