Because if there was an ounce of truth behind this at all Republicans would stick to it and get rid of all the Democrats in House/Congress and it would be the nations biggest scandal.
If Republicans were already in on this, they wouldn’t need a big shooting to propose laws as together with Democrats they would have the majority of vote to pass whatever they want.
Putting any thought behind this makes the conspiracy theory ridiculous.
How about this crazy theory. Crazy unbalanced kid who was home schooled and mommy issues shot her up and the kids that she loved more than him?
Thats deeeeeep man.
