From WND.com:

Quinn was targeted by police because his son – who was suspected of possessing drugs – lived in the same home. His son was absent, and police records reveal they knew that fact when officers broke into Quinn’s home in a no-knock, SWAT-team style forced entry.

The state admits the raid was based “solely on the suspicion that there were legally owned firearms in the household.” (emphasis added)

But registration of firearms won’t lead to government abuse of power or confiscation…..
