the guns break down into 20” or smaller pieces. 4 suitcases, 5 or 6 guns each. Another 6 suitcases for the ammo/accessories.
The shooter anticipated being able to shoot for longer than 10 minutes. It appears he grabbed a new weapon instead of reloading. He anticipated the barrels melting/warping. So, yes, he would need more than a few guns to light up 3000 rounds or whatever the end count turns out to be. The number of guns found in his home(s) are immaterial and the only real reason to include them in the count is the ‘fear factor’. In reality, a person can have a hundred guns and be no threat. Or one and be a murderer.
That said, maybe he didn’t bring all the guns up. Maybe, someone brought some to him to sell. He had a large (to us) sum of money in his vehicle. Nobody’s said what he had in his pocket. And not all the guns trace back to him. For sure, we know that some of the ammo was bought by someone else. Without hall tapes, at the very least, elevator bank tapes, we don’t know all the puzzle pieces.
BTW, in all the timelines, I haven’t seen anything tracking the time to open the windows.
Note these are not operable windows. The had to be opened with a hammer and glass removed.
If the glass fell, then that would begin their timeclock on being exposed or their intentions made public.
It probably would take 2min-30 min to open up those windows without the glass falling and exposing their position.
On the other hand, if actions occurred exposing their position, then it still might take several minutes to clear out the glass window, in total disregard of the glass falling below. Glass windows falling 30+ floors would attract attention.
Brings up another issue.
Did the taxi cab recording have any recording of the glass windows falling nearby the cab on the roof?
