The police report in the incident does not list any guns found at the Harris home
If our "laws" actually followed the Constitution, as they are supposed to in order to have ANY authority at all, a complaint that you saw your neighbor walking around with a gun would illicit a response of "so what?". Not a raid in which the cops end up shooting the family pet.
Again, we don't know what the complaint was, they don't say here the exact nature of the complaint. Not all complaints pan out, but they nonetheless have a duty to investigate. They did not raid, they were in the yard.
