We have gun laws, laws against shooting people, etc. We also have heavy penalties for breaking those laws, so I’m not sure what point you’re trying to make. The issue isn’t a lack of laws, since those clearly exist.
I also find your argument disingenuous, since when Democrats talk about “gun control,” it is always in terms of banning/confiscation. I don’t recall any calls to ban SUVs because some dimwit ran over a bunch of old ladies in a parade a few months ago. Therefore, it seems to me that Democrats are standing on the graves of children to push their agenda, rather than trying to actually solve the issue of people wanting to mass-murder others.
