Statistically speaking, people that have conceal carry licenses are less likely to engage in criminal activity than the average person, and less likely to shoot a person in general. The people to worry about are the people that carry firearms without having a valid carry license. (This doesn’t apply in the relatively few states that don’t require permits to carry concealed firearms.) Essentially, people that obey one law–getting a permit before they carry a firearm–tend to be likely to obey most laws.
