The result of this idea from the folks who hate gun and gun rights will bring with it tragic and unintended consequences.
Lots of law enforcement folks practice on their own time and at their own expense. The same holds true for the thousands of security personnel, private detectives and ordinary people who need to defend their families along with themselves.
None of these people will be able to afford to train and practice as a result of any punitive tax. I wonder how many innocent people will have to die because of government imposed, poor marksmanship? Of course all of the firing ranges will have to close and even if you could afford the ammo tax there will be no place to practice.
The legendary, Congressional Medal of Honor winner, Sgt. Alvin York did not learn his shooting skills in the Army. He developed his ability to protect our way of life as a civilian. That was long before we wrapped ourselves in thousands of gun impairments and gun bans.
This punitive ammo tax idea comes from the same people who want guns banned from the earth at any risk or cost. These emotionally lost souls all gather under the banner of, Sensible Gun Control. Their idea of sensible gun control is for the unrealistic concept of total gun elimination from the earth.
