An eMail I sent to Walmart

My sons want to participate on the local  School Trap Shoot Team.  In order to do this - they have to use a GUN to shoot the clay pigeons.  I went to Knoxville Iowa Walmart SUPER store.  The employee said I was not allowed to buy a gun - he refused to sell me a gun, because it was for my sons and that was illegal and he would go to jail.  
I would like you to explain to me how a local high school has a shooting team with over 50 individuals who are breaking the law.  Wait - you can NOT do that because it it NOT illegal for a parent to buy a gun and register it in their own name and allow their child to use it for a lawful activity.  
I'll refresh your memory...

Mom to 2 young men who WILL be using GUNS to shoot on the Trap Shooting Team
We will be buying our guns at another store - a store who educates their employees on the state laws.  ​

Poor ignorant Walmart employee - I wonder if it is his fault or the management's fault?  Another thing I noticed... I walked away instead of educating him.  This is going to be a long path I walk, trying to unlearn my behaviours that have been ingrained into my head these last 20 years.  I stood there looking at the toothless man KNOWING that he was absolutely wrong.  I said "really?"  he said, "yup."  I walked away.  Makes me so mad at myself.
