The problem with your "lax gun laws" theory is that your friends and neighbors who own guns aren't the problem. Limiting access to firearms only works with honest people, and they aren't the ones committing the crime. This is why gun control efforts always fail, because you are only preventing good people from protecting themselves, and disarming honest citizens won't make the dishonest ones less dangerous.

If you want to reduce gun crime and violence, then you need to be working towards correcting poverty, addressing gang violence, improving mental health care and providing a real economic option for kids growing up now to support themselves.

Stripping the rights of normal folks won't do that. Never has, never will.
