John's machete and the magnum rounds (spoilers)
Anybody notice that after his machete was confiscated, he took the time to take it with him to the helicopter?
Also, if he took the time to get the machete and Rhodes' two magnum revolvers, why didn't he take the multitude of rounds on the bandoleer? Just take the entire bandoleer and then no need to throw away the beautiful magnums. In fact, even though he ran out of ammo, why didn't John keep the guns in case he came across more ammo? I doubt they never will do more supply runs.
