Wow, this didn't say that it had anything to do with hobbying, but I certainly get your point about inviting folks into your home. If I remember correctly there are some areas in WI that are so rough (too many bad things happening etc.), P411 put out an alert.
Unfortunately Hungryhippo is correct. If LE would focus on the REAL crimes.... I know after repeatedly being victimized a lot of folks live under surveillance and carry. It's too bad that we have to live like this....
