I don't think trespassing on open property is inherently threatening - I doubt the manual labor employees were at any time in risk or threatened by the protestors, maybe I need to do more homework, but this still isn't holding up. If they forcibly enter a locked building, that's also different than crossing a fence. If they force open a building and sit in the lobby with a sign, that's still different from forcing themselves further into the building, or causing destruction or damage to irreplaceable property (computers/data/private information). All of these things should require a different level of awareness of context and response magnitude by officers. Comparing them does nobody any good unless we're laying out the different levels of force/response we think is reasonable at what level of crime and at what cost to taxpayers or businesses. I don't really want to have that conversation because it's moot if we're starting at cops using "less than lethal" which isn't non-lethal, force against unarmed fence climbers. Just full stop.
