I think you owuld understand her point very clearly if you could manage to find the video. We can destroy our country and our constitution, or allow it to be destroyed if we do not stand up to injustice, rushes to judgement, and being intimidated by the "authorities", be they congressmen, the police, or even some lawyers!
The fact is there is evidence of Danielle in DW's home and RV and possibly of him and/or his home/RV at the Dehesa site. It is not unreasonable for some to think the police arrested the correct man. It remains to be seen if the prosecution proves their case beyond a reasonable doubt, but so far they've done a good job.
We can disagree without being disagreeable and saying some care about the Constitution (implying those in disagreement don't) and saying some are on par with terrorists.
