Bottom line about this is that team Trump did offer the additional resources needed to prevent the whole ordeal and Bowser did not accept the offer. That's a fact and no amount of spin is going to change the fact. So all of the blaming Trump for causing a riot is something very emotional occurring in the heads of those that hate the man and want to see him fail at everything he does, including standing up for what he believes and supporters who support justice for all and not just one side.
Here is what Trumps chief of staff had to say about that offer. It was not an order, it was an offer.
A former Pentagon official with the Trump administration, Kash Patel spoke to Jan Jekielek about how the Capitol riot of January 6 could have been prevented. Patel, who was Chief of Staff to Acting Secretary of Defense Christopher Miller, said "We had offered the Capitol Police, and Mayor Bowser of Washington, DC, thousands of National Guardsmen and women, two days before January 6. And they turned us down."
So when you look at all the fact checks on this, they always refer to the fact that no order had been given by the president. That's a clever spin on the point at hand, the point was that it was offered to them and they refused so of course no order was given, they didn't want it. But if you fact check something that's really not in question, it sounds like he lied somehow. That's called spin. You can spin what happened like a top and people just remember and regurgitate the spin as if it were what really happened or mattered. They didn't want any extra help because of the optics, plain and simple.
Brad Parscale had an opinion, everyone has one but that doesn't carry any evidential weight as the man ascribed things to a single person based on his own emotions and nothing more. There is nothing reasonable about ascribing blame for someone's death on a rally about justice for all the people. If you or anyone else think that it was a call to violence, that is something you made up in your head to justify your hatred for people who stands up for what they believe. Last time I checked, that's a virtue, not a crime to stand up for what you believe. And getting shot for it is patriotic.
So if Trump didn't cause this, who did? The same thing that causes any other protest, injustice. There was a laundry list of injustices in many many things that led up to the election, and more and more injustices continue to this day without hardly anyone to stand up against those who would have us continue to go down the path of corruption and injustice. All the corrupt judges that wouldn't even look at the corruption taking place as a whole, they only wanted specific evidence that was irrefutable in their eyes which is absolutely impossible to gather in such a short period of time and under the circumstances. It was the failure to even look at the evidence and simply declare that the election was the most secure election in history that caused the desire to protest, not the president himself. That is truth, plain and simple.
