If all the shooters were cops, if it was in fact a “sniper ambush” using an u/c fake biker cop as “bait” for a provocation, then every cop involved in the shooting could face murder charges down the road.
This will cost Waco untold millions.
Your theory sounds very plausible and does fit with what little bits and pieces are leaking out. I don't know if you could get murder charges, accessory to murder, accessory after the fact, etc. to "stick" to all the LEOs involved in this. Certainly anyone who discharged a weapon is likely to face murder charges, pending ballistic evidence...
Any LEO that participated in this fiasco and the ensuing cover-up ought to immediately lose their job, retirement, everything. They can never again be trusted with a badge and a firearm. We need to send a strong message to all LEOs that yes, they will be held accountable. This is not just for the public's benefit, it will help un-tarnish LEO's image. That image has been suffering under the weight of too many highly public, highly militarized incidents. It has also suffered from a few over-publicized incidents where law enforcement was beat up by race-baiters.
