Come on, we all know there are gun sales being made without background checks. It doesn't take too long to find someone who is willing to sell a gun "no questions asked".
Don't come the old "enforce the laws on the books" since the laws are
set up so that it is next to impossible to prosecute these people.
Anything which might prevent these sales are opposed on the basis that
they "infringe upon our rights."
Or "criminals don't obey the law".
OK, if criminals don't obey the law, let's get rid of all laws.
