Are commenters here familiar with the history of police and "private security" being deployed against striking workers? This has been happening without interruption in the U.S. since the nineteenth century. There are some excellent resources out there - some useful keywords to search would be "Pinkertons" and "Ludlow"… It's useful to recognize that police primarily exist to defend private property and the persons to whom said property belongs.
