"Shall Issue": The New Wave of Concealed Handgun Permit Laws
This is probably the most comprehensive study on the effects of concealed handgun permit laws that I have ever seen. It references two other papers, covers EACH states conceal and carry laws, and addresses many arguments that gun control advocates bring up.
It does not bring up suicide, but does seriously address the legal issues associated with barring concealed handgun permits.
The actual study part is fair and balanced.
In the states discussed above, the dire warnings of the gun control lobbies were not realized. It should not be surprising that the carry laws appear not to have a noticeable impact on the homicide rate in most states (Florida, perhaps, excepted). To begin with, it is important to notice that in most of the states studied, the general rise and fall of murder rates before the new laws took effect roughly approximated the rate in the rest of the country. This suggests that, in general, the causes of changes in murder rates are largely determined nationally.
But several other parts seem fairly biased, even to me.
To me this was the important part.
"It is well-settled American law that the police have no legal duty to protect any individual citizen from crime, even if the citizen has received death threats and the police have negligently failed to provide protection."
I did not even read all of this, I ran out of time and energy.
