The information below was part of an earlier post, but I consider it important enough to have a post of its own.
Leftists are pushing back hard on the belief that right-to-carry laws deter crime. Some liberals and liberal institutions (like a professor at Stanford University) are publishing papers that say the opposite is true: that more guns means more crime and violence. See conclusions of the Stanford paper here.
Intuitively, the professor's claims do not make sense to me. If criminals know that a neighborhood has guns, would they be less likely to do home invasions or burglaries? If criminals know that there are right-to-carry laws in effect, would they be less likely to shoot up schools and theaters? I would think so. What makes less sense is that otherwise lawful citizens turn into criminals when they have ready access to guns. Absolute bunk, but liberals will believe anything.
REBUTTALS: I found two sites that rebut the Stanford study as sophomoric and biased. No surprise there. Read MORE JUNK, LESS SCIENCE: New Stanford “Working Paper” claims right-to-carry increases assaults by 33%
Also read: Right-to-Carry Gun Laws Linked to Increase in Violent Crime -- a rebuttal.
If liberals throw the Stanford study at you in argument, refer them to the above links. The Stanford study is superficial and highly biased.
