How many firearms do you suppose most people have that weren't purchased in a store?
Some years ago I bought a couple legal weapons at a well-known outdoors store.
I was traveling, and my bag was stolen.
I wanted to report the crime, couldn't access my receipts or serial numbers at home.
I called the store, gave them my name, described the firearms. Ten minutes later the guy was back on the line. "I have the purchase record here, are you ready to write down the numbers?"
Those records exist and can be accessed. They WILL be accessed when the Left takes the reins.
The left WILL NOT take the reigns. I predict President Trump WILL be reelected in 2020. The left is shooting themselves in the feet (pardon the sarc ).
