If you want to carry a gun in the US, you need to go through a background check and there is often a training requirement as well (regulations vary by state, with AK and VT requiring no permit to carry a concealed handgun).

One problem with "regulations" is that they become very restrictive and then only the elite are able to obtain them. NYC is a great example. If you have a lot of money or sway with the mayor's office, no problem, here is your CCW. If you're just a regular joe? Sorry, not gonna happen.
