Trail cams on private land

[pitw]

What the [L] is with some folk? Was over checking on the grass on a pasture and found not one but three trail cams.
When I'm asked for permission to hunt I always state no cams but it seems people just don't care what the land owner wants. Do these same people think it would be alright for me[or anyone for that matter] to up trail cams in their house? Thinking I'll shut down permission to only those I know as I'm sick and tired of idiots.
