Boulder had an assault weapons ban that was in place for two years and a lower court judge struck it down. It was then challenged and to be put before the Colorado supreme court. 4 days after that happened, and before it went before the supreme court, "assault weapons were used in a mass shooting".
Like clockwork. It's another fake shooting to influence the courts. Predictable. It could not possibly be more predictable.
No one would magically come up with an assault weapon complete with ammo during an ammo shortage and shoot'em up in four short days, when most people would not even know a judge ruled in their favor. Most likely this is another case of crisis actors.
