UBC ... the slippery slope to gun owners who can't prove their innocence

Don't be fooled about UBC (Universal Background Checks).

The problem isn't about knowing who has what guns;  the problem is about who has a gun which the state may unilaterally decide to confiscate.

"Oh, they wouldn't do THAT!"

Bullshit.  California did exactly that in 2015/2016:

REDDING, Calif. - A new California law takes effect January 1 that allows legally-owned guns to be confiscated if family or friends believe the owner is a threat to themselves or others.
It's called AB-1014 and it comes after the mass shooting in May 2014 that claimed six lives in Isla Vista, California.

(And by the way, Oregon is toying with the same legislation ... it's so NICE to live in a Liberal State!)

Why would your 'family or friends' turn you into the Confiscation Cops?  Because they love you!

And you're going to jail, Buddy.  Isn't love wonderful?

The Problem with Universal Background Checks *(UBC)* is that it is tantamount to Universal Registration ... which is the first step to Universal Confiscation.

Lawsuit Filed Over Unimplemented Universal Background Check - Bearing Arms - Anti-Gun Laws, Gun Control, Nevada, universal background checks:

The problem with universal background checks is that nothing about them is particularly enforceable. The transfer of a firearm to a family member is just one example. Unless the state maintains a full database of who has which guns, it’s impossible to determine just when a gun was transferred and to whom. 

That's not a 'problem'; that's a FEATURE!

Why do you think The State needs a "full database of who has which guns"?

Because they want to know just which doors to knock on, and which guns they can confiscate there.  And if they don't find the guns their registration database tells them they should expect, you're in a heap of trouble, Bubba!

Oh, someone stole your gun(s)?

Guess what ... there's a companion law requiring you to report gun  thefts within x-number of days.   You didn't notice they were gone?  Sorry ... put your hands behind your back, and tell your wife and children goodbye.   You're going to jail, Bubba.  You'll have to prove your innocence.

Personally, I couldn't tell you how many guns I own, let alone how many of which type.  Serial numbers?  Some  most ALL of them don't have serial numbers. 

"I don't need no stinking serial numbers!"

This isn't America.  It's California, and now Nevada, and (coming soon) it's Oregon.

I didn't vote for this, in Oregon, my Native state.  It's to be a 'regulation', not a state constitutional issue.   Second Amendment be damned.   "We don't need no stinkin' Second Amendment."

"Liberal Politics" isn't politics;  it's "Hi!  I'm From The Government and I'm Here to make sure that you understand that we own your a**!"

Some folks don't appreciate their efforts.
