"it sounds to me like they were shooting at guys running away in vehicles" - that makes sense given what we saw.
But the firing was without any doubt from north to south, in what appeared to be near the Hut. The tracers were coming down at about a 30 degree angle, then there was flak flying around from whatever they were shooting at.
But there is no question that the ricocheting bullets, based on the tracers, were travelling from north to south at about a 30 degree angle up, then disappeared to the west of the Spa.
This is what we saw, but we will likely never hear the whole story. Bottom line is that this operation was conducted without little concern for the local residents, tourists or staff - no matter the reassurances that no one was in danger - it was too close for comfort.
I tried to upload some pics I took, but continue to get error messages. One of them from 11:00 am shows two marine trucks with machine gun mounts in the rear patrolling the lot of the Spa - clearly they still though someone was on the loose.
