Have you even read some of the written charges for the people being locked up, I think close to 650 now. 129 have pled guilty … And many of them have arrest warrants and detailed criminal complaints are listed on the web so I can provide the link and you’ll see that in so many cases it’s anything other than “minor crimes” and just a light touristy stroll in the park.

You can charge people with anything you want.
And if you were kept in solitary for nearly a year in a festering DC jail with no chance for a bond, you'd plead guilty to anything.
