The reason that guy and you can't come up with a good response or debunk the old saw about guns not killing people is that is it the truth. The reason it upsets you so is that the truth hurts. That was both pathetic and hilarious. You claimed there was a correlation between legal access and rates of homicide, there is such a correlation but it is the opposite of what you claimed. the more guns Americans own and the more places they are allowed to carry them the fewer gun homicides we see.
It was especially funny how you claimed that guns needed to be regulated like cars and then you listed off a list of regulations for drivers that are not regulations of cars at all. You did a really great job at explaining how drivers kill people not cars so to control that we regulate drivers. Thanks.
Here is the point, gun laws that affect gun criminals, like for example locking away people for long periods who commit gun crimes, are very effective.
But those are never the types of laws you and the caller call for, you want laws that affect legal gun owners and guns, these laws have been tried and fail every single time to have any effect because neither guns nor legal owners are generally the ones committing crimes.
about 1 in 10,000 people is a habitual gun offender, any law that does not target that person, in other words any law that affects what law abiding people may buy or how they can use their guns, has zero effect on gun crime or homicide because they don't affect gun criminals at all.
