Baseball bats and lawnmowers would be violence. Factory reset and reconfig is just maintenance. I could even charge the government for my services.

Defacing federal property.

I mean, I agree that Antifa should be compensated for making the federal building look better, but the feds don't see it that way.

I would wrap them in protective signal blocking boxes out of harms way. Charge gov service fee to open box.

while in fact there's still a possibility you jeopardized an investigation that could save lives.

The basic idea here is that they are using cameras to place the property owners themselves under surveillance, not to surveil others from that property.

I remember 2 cams were installed, 1 was on tenants, the second one one some pathway (that would include the tenants moves eventually?)

All this is unclear, something happened, maybe the owner knows or not. This story should be taken with a grain of salt.

Take it to its logical maxim

If the government has the right to enter your property and place cameras on it to surveil you and you aren't allowed to remove them, just how far can they take that?
Can the government send in a small army to occupy every square inch of your property beyond the curtillage, build surveillance equipment and walls all around you and set up towers with searchlights and guards carrying rifles?
Can they physically block you from leaving your property, since any attempt to do so would interfere with their surveillance operations?
Can they bring in bulldozers and cement trucks to cut down all the trees, plow the ground and lay concrete and build forts and barracks on your property to house the military units that will occupy your land?

If they're putting cameras on MY property without informing me, they're surveilling me, not others who don't reside on my property. And if I find the cameras, they become my property, as they were found and left on my property.

2 cameras were discovered, there could have been even more. The probable idea behind putting a camera on a trail is to see if the property owner is obeying hunting laws on his personal property.
