Around here, if a person is in his house and police arrive and there is stolen property in his front yard, since they can't prove the person had knowledge of it being there, they can't charge him with stealing it. Even if they are outside and say they found it there when they came out and were planning on inquiring around the neighborhood, they don't arrest him for stealing. The latter could be considered possession, but they also realize the weaknesses if the person claims they didn't put it there, but someone else must have tossed it into their front yard. Basically they have to catch the person in the act, or have witnesses that saw them remove the stolen object to get them to arrest and prosecute the person. If that rule was applied in Utah, then I wonder if they could still go around swabbing door knobs and use that as an excuse to get search warrants. The situation I'm thinking of is one that actually happened where some bikes were stolen and later found laying in a yard. The person whose yard they were in was an older retired person, obviously didn't take them, some kids had dumped them there after being through riding them. So, the police take stolen property found in your front yard, but due to anyone able to leave it there, unless they have proof the person who lives there took it, they don't arrest or charge them, not even for possession of stolen goods. Possession here means you must have it someplace other than a common area that anyone can easily access.
