This would work in my neighborhood. People go nuts when a random dog walker drops a bagged dog-poop in their trash cans. (bagged poop must be in a larger trash bag). Someone could make a killing if they just decided to specialize in all the houses in this neighborhood that were built at the same time by the same developer. We all have the same issues pop up at the same time.
That would piss me off too... it's trespassing, and mirrors the conceitedness of less conscientious pet owners who just leave their dog crap on the road (carry your damn poop home and put it in your own garbage can mkay?)
Really? You are that possessive? Besides, how can it be trespassing when the can is at the curb (I would not like someone coming on my property to do so - agreed there) and likely in the public right of way? Also, in my area we do not even own the can, the city does. mkay...
It's not a possessive thing, it's an invasion of personal space thing. The fact that I'm required to put my can at the curb for collection is not an invitation to use services I have paid for, for free. The can should be closed prior to collection, and opening it is certainly an invasion just like opening my accidentally unlocked car door when parked on the street.
I was contemplating trespassing because a can is on personal property, what, 99% of the time? I don't know I don't even have one. But I don't want your junk fliers on my mailbox, don't want your dog pee on the tree in front of my house, and don't want you to externalizers the social costs of your fetish for small animals.
Sometimes I think dog owners are like new parents, in that they think they are exempted from the rules just because they have a cute little thing. You get the benefits of a loyal companion and take him around town to pee and shit all over. If it's really onerous to hold onto that poop bag until you are home or at a public trash can, maybe you aren't responsible enough to take care of another living thing. If you think it's no big deal, then just don't do it. Clearly there are people who care, so why be a jerk and insist on imposing your fecal matter on others, or threaten to put it in their mailbox?
Edit: regardless of can ownership or location, I am responsible for the can. If you are not trespassing, you are illegally dumping (unauthorized disposal). I may not own the sidewalk in front oft house, but I responsible for its upkeep, and I don't want your poop there either, mkay?
