We, Arizona, were the third state to pass "constitutional carry", which was made law in 2010.
One of the numerous beneficial elements of this law, is that those who may be unable to obtain a CWP because they can't handle the financial, as well other imposing factors, will now be able to do so. Maybe they don't have the time, or even transportation available to get to and from the range. What ever the imposition, it's not fair to impose such regulation that would make carrying a self defense weapon inaccessible to average law abiding citizens.
When this wonderful law went into effect in my state of Arizona, it brought with it long needed changes to our self defense laws, and it brought much needed change to the sentencing laws for violent offenders as well. Prior to the new law, our self defense laws were seriously flawed, which resulted in a number of truly innocent people being sentenced to prison for doing nothing more than defending their life, or that of another. Following the new law taking effect, a number of individuals had their convictions over turned, and as a result, they were subsequently released from prison.
So IMHO, in order to achieve it's full potential, "Constitutional carry" is an entire process, not just a single revision in state law concerning who can carry, and in what manner.
