>After leaving the Bureau, in 2005, he started the Soufan Group, a security-advisory firm in New York. His company runs a training academy for police and intelligence forces in Qatar, a neighbor and bitter rival of Saudi Arabia.

The beginning of the article would have you think that this related to Soufan's anti-terrorist work. However, reading more it seems that this is related to his employment by Qatar. There is somewhat of a cold war going on the the Middle East between Saudi Arabia and Iran and this seems to be related.

Soufan is basically a mercenary working for a foreign government(Qatar) that another foreign government(Saudi) wants to do in. Even the article does not talk about any intention to kill him in the US, but in Qatar.

This is very different from what happened to Jamal Kashogi who was a journalist and not involved in military or security affairs.
