It was all for one reason and one reason alone; to obtain laptops containing damning evidence against the conspirators. If true, and Trump does have Nancy’s laptop, imagine what could be found on it. The brilliant move by Trump was that he figured there was only one way to separate the person from their computer and that’s to intentionally incite violence. The only thing these people care about more than taking down Trump is their own personal wellbeing. Threaten that, and take the laptops. What comes after that remains to be seen.
