That’s an interesting theory. The Cossacks weren’t invited to they are definitely FBI under cover agents. Did they also plant the 118 guns that were recovered? Even for Texas that is a bit above average.
I believe most of the guns were found inside saddlebags or pickups..
As with most brawls, (at least the ones I am familiar with) guns are generally a no-no. It is customary to use nucks, chains, or most commonly fists. Knives only for the Puerto Ricans..
My guess is that the gun play began with the uninvited.
The cops who were already on scene, called in SWAT, and SWAT likes to use it's toys. So they did. And that ended the brawl on a rather dismal note.
There may be one or two deaths associated with the brawl, if that, and the rest are the responsibility of the SWAT teams who reacted with too much force against a bunch of guys with jobs to go to the next day, some Abate reps, and a few macho types who were the target of the uninvited guests..
