they are not free. Gun shops charge a fee, anywhere from $25-$50 depending on the state. Some may waive the fee, it’s up to the shop because the fee is more of a process service expense for them.
Yup.
Even worse, seeing a nice revenue stream some states now add fees they personally pocket on top of what the dealer charges to do the check... and some even add fees requiring a check each time you buy ammo making even target practice harder for those less well off.
It's basically a poll tax but for your 2nd amendment right instead of your right to vote.
Paying $50 in "transfer" fees on top of the cost of a cheap pistol is a pretty hefty tax to exercise your right to self defense.
And given how disproportionate poverty is among minorities these end up discriminating along racial lines too...
(indeed, MOST gun control laws going back over a century were fundamentally racist in origin- things like requiring your local sheriff to approve a purchase or carry permit for a firearm for example and you could be denied simply by him finding you of poor character... and strangely enough the color of your skin seems to highly coincide with such a finding...it's only in the last decade or two most states have moved away from racist policies like that and become "shall issue" instead of "may issue" and some still haven't entirely given it up because they still charge for permits and it's again a nice lazy revenue stream even if it benefits nobody else)
And as mentioned many studies show it has no actual impact on reducing crime...
For example-
A study published in July 2018 found no association between firearm homicide and suicide rates and the repeal of comprehensive background check laws in TN and IN.
An October 2018 study conducted by the Violence Prevention Research Program (VPRP) at UC Davis and the Center for Gun Policy and Research at Johns Hopkins Bloomberg School of Public Health found no change in firearm homicide or suicide rates in the ten years following California's 1991 implementation of comprehensive background checks
(that 2nd one is particularly useful because it uses the 32 states that never had such background checks as a control group to compare against the 10 years before and after the 1991 CA law... often pro-background-check studies will just show a change in a single state that when you step back you realize is reflective of a broader change rather than causative from the background check law)
