The long black bag looks like a smallish wrapped up body to me, knocked out not dead? As apparently it's medical supplies that get thrown out of the front onto the pavement, for them to take into the back for the journey. Cop also got big bag on back, maybe weapons, or that protective gear srayzie mentioned. Then Cruz's younger brother got taken into 'mental health custody' didn't he? I dunno .It made me wonder. They had a similar upbringing, surely. Cruz looked off his head when arrested, unable to stand. Not often that US police trank shooters rather than gun them down is it? If there was a second shooter, or patsy, they'd need to get them out of the building somehow, would't they. God bless all involved, MK'd victims included.
