Sayid is an Other/Dharma member

1. Sayid knows Inman (who was Inman's hatch partner before Desmond?)
2. not seen on airplane or airport
3. Let Gale go out of net and was going to follow him
4. Only wanted Jin to go with him to ambush Other Camp (I'd take as many people that would go with me)
5. For an Intel guy I'd have walked that Island by now
6. Why was he not worried that Gale's map was a trap. (took Kate & Charlie?)

Sayid was in the airport. Shannon had him searched by security in Season One.

I don't think so, here's why:

1 and 2:
Sayid was shown at the airport before the flight. Shannon got him in trouble with airport security and got him cavity searched. I believe he referred to this later when they were doing the couple thing on the Island. She may or may not have admitted to doing it to him.

If you consider what Kelvin Inman said to Desmond in the finale, he might actually be Joe Inman, but changed his name. I wish Sayid could have met him! I know Joe Inman had a major effect on Sayid in Iraq, but I don't think that leads to Sayid being Dharma. When him and Joe parted ways it was not as friends, why would he go to work for him again?

With that said, this is Lost, so who the hell knows?

3:
Sayid also discovered that Hoax Henry was an Other, when the rest of them had no clue. Remember he worked HH over in the lockup and then told him how he became a torturer. Why would he do this if he and HH were old buddies, and especially if HH was the Leader? They could have talked about the American Idol finale in there for all anyone would ever know, but we were shown that was not the case.

4:
Sayid didn't want to bring a large posse because it was a recon, not an ambush. Recon travels light and quiet.

5:
To be fair to him, he also had a few bad things happen in his life recently, and again I doubt it was because he was an Other. If anything, he is sticking close to his friends (or as close as he gets to them) for support in order to keep his mind together.

6:
That one I don't know - maybe to feed Charlie to the Monster if it attacked them or trade Kate to the Others as a sex slave. Just kidding! I really can't answer that but my best guess is he really did think it was a lie and that there was no threat.

Sorry! But, Sayid is not part of Dharma.

1. So he had a past link with Inman. It's not like there are no past links between characters. We see them all the time. Jack knew Desmond before the island. Is Jack an Other?
2. Yep, he was at the airport and on the flight. Don't you remember Sawyer and Sayids fight first season. Sawyer discribed how he was watching Sayid all during the flight. and yes, Shannon turned him into security before the flght even left the ground.
3.He let gale out? I would not want to try to questio him out in the middle of the forrest. Your leaving yourself open to attack from the Others. You have a ready made cell at the hatch the numbers are on your side there. Hello! He kicked H-H butt. He took Sannons death out on him.
4. Why bring sun a pregnant woman suffering from mornning sickness on the trip if you didn't have to. He would have liked to have gone alone. The trip was all about stealth and the less people the better.
5. The only person I can think of that has searched more of the island than Sayid is Locke. He also has "The French chicks" maps.
6. Sayid was the one who questioned the validity of H-H map. Saying, Just because he drew some of the land marks dose not mean he's leading us anywhere. He also refused to believe HH even in the face of the ballon and grave. He dug up the real Henry Gale and later tried to shoot H-H. He would have done it if it wasn't for A.L.
Sorry I just don't buy it.
