You're supposing that carrying a gun makes a person more at risk than someone who is not carrying a gun.  If someone is attacking you with a knife, what would you rather have to defend yourself with, a bagel or a gun?  A 100 pound woman is being attacked by a 200 pound man, what would she rather have in order to defend herself, a police officer who is 10 minutes away or a gun?  What do police officers and soldiers use to mitigate the risk of an attacker armed with a gun?  They use a gun.  I will unapologetic-ally always recommend using a gun to defend against someone with a gun.  Until you can assure me that all criminals will disarm themselves of guns, I believe it is risk mitigation to carry the same device as the perpetrator.
