Wise point Griff1315! Opening anything but the popular tourist destinations, (and as vaccinated as possible) is the only real reopening Thailand should consider. Until such a stage as the general population has 80% or better of the population over 12 years of age vaccinated, opening is fraught with danger and a surge in cases the Thai hospital system could never cope with.
Sorry about that, I'm trying to be patient and informative but my patience is being tried to the limit!
The guns for that particular shoot had apparently been checked by the armourer, Hanna Gutierrez-Reed, before a lunch break and put on a cart on the set where they appear to have been left unsupervised. After the lunch break, off set, the guns do not appear to have been checked again and one was picked up by Dave Hall, the assistant director, and handed to Alec Baldwin, telling him and the crew that it was a "cold gun".
Reportedly none of those who handled the weapons on the set, including the propmaster and the armourer, were members of Local 44, the propmasters and armourers' union and not only was the armourer inexperienced as i've described before but she was also unlicensed as required by IATSE .
According to CNN and the Associated Press, Dave Halls, the assistant director who handed Alec Baldwin the gun, he "was fired from the 2019 production [of 'Freedom's Path'] after a crew member suffered a minor injury "when a gun was unexpectedly discharged.” The producer, who asked not to be identified by name, wrote that Halls “was removed from the set immediately." Production did not resume until Halls was gone."
As @Marc26 mentioned before, it's now been reported (but not confirmed) that the set guns had not only been used by the crew for off-set target practice, but the live rounds used which should never have been brought on to the set had been stored with the shoot's blank rounds contrary to all industry standards and rules.
While reported as "misfires", stand-ins for Alec Baldwin had previously had two accidental discharges on set, coincidentally with the same gun only a few days before which had not yet been invetsigated with no action taken, and crew members had walked off the set in protest at the lack of safety precautions.
It's not just one instance of negligence or even a string of unfortunate coincidences, but a whole string of constant negligence and disinterest in any form of safety, regulation and checks.
