Really? Any evidence to back that up? Since the 1990s over 30 states have added "Shal issue" laws concerning ccw permits. Has the violent crime rate gone up in any of those states since then?
Florida has over 2 million permits that it issued since the mid 90s. Has their violent crime rate or murder rate gone up? No. quite the contrary, it has gone down.
Your claims lack valid evidence to support them.
There's no evidence in support of any of this.
There is no evidence citizens carrying concealed weapons results in a rise or decline of violent crime.
Moreover, it's legally and Constitutionally irrelevant – citizens have the right to carry firearms pursuant to the right to lawful self-defense; citizens are not required to 'justify' the exercising of a Constitutional right as a 'prerequisite' to indeed do so.
