I agree with you.
Do you recall Andrew Brightbart's undercover video in the ACORN office?
Suppose the anti gunners find such a shop,make "inside the gunshop" vid,and get it on network news,or before Congress.
So,if I were a firearms manufacturer,like Ruger or Glock or S+W,or Colt,would I want my product line smeared by a shop like that?
No.That shop might find they cannot get anything from the distributors anymore.
Beyond not shopping there anymore,contact these guys:
