I don't doubt he spotted "someone". I pretty much give everyone the benefit of the doubt until proven wrong.
Thanks for admitting I was there.
The tip-off was he gave a speech in front of about 1000 Somalis, and he was driving around in his Brown Mercedes SUV. Only person in the city with one. There were very few vehicles in Moghadishu other than farmers taking produce to market, technicals which were his soldiers, and UNISOM vehicles.
After we buzzed the rally he drove straight to CNN headquarters to escape. They hid him till we had to return to the airfield for fuel.
One other time we may have spotted him and some SEALs Fast-roped in but he got away. They decided to give us a Barrett Light to shoot into his engine block next time we saw him. We practiced on it and one evening my team killed a technical rig when they were fired upon.
