This is going to be short. Here are some reasons why I am skeptical of any registration regime. These are off the top of my head and in no particular order.
The Trail of Tears / Indian Removal Act
Detention of Japanese Americans
Indefinite detention of US citizens
No knock warrants
Militarization of the police force
US airspace open for drones
The TSA
The Department of Homeland Security
The Guantanamo Bay detention camp
Enhanced Interrogation / water boarding
Warrantless wiretapping
No fly lists
Wounded Knee
Jim Crow laws
Black Codes
Prohibition
The Tuskegee Study
Eminent Domain
Dred Scott
Patriot Act
These are just some of the things that our state and federal governments have done to the citizenry of this country, and you expect me to trust it enough with the names and addresses of every firearm owner in the country along with the number and types of firearms they own? Sorry, that is a step down a path I am simply not interested in. I have zero confidence that information won’t be used to target lawful gun owners at some point in the future. Call me paranoid, I don't care, I've got the evidence that shows what our elected government can do, has done and continues to do. Y’all need to find a better way to control criminal behaviour.
Please note, I am down under and it is time for sleep. No comments from me until tomorrow.
