Does "enforce existing laws" include adequate funding for the Bureau of Alcohol, Tobacco and Firearms, which has been demonized as a bunch of "jackbooted thugs" and had its budget cut by gun rights members of Congress?

Also, what about gun shows? Most states place few or no restrictions on unlicensed private sellers who can sell to whoever they want with no background investigation required. The guns involved in these transactions often cross state lines to be used for criminal activity in states with more restrictive laws.
