Helo OP vids posted prior
There's 2 clips of Helo OPs in downtown LA from (pbs)
One from a news crew here >>5068942 (lb)
and one from private citizens >>5068364 (pb)
Both happened over the weekend, but are 2 different (1 on the 4th, 1 on the 5th)
I would guess they staged several training exercises to cover an actual OP
The private vid (attached) clearly shows the guys loading something heavy onto the birds from what appears to be Wells Fargo (previously discussed).
