Gun control laws don't work. It's simple to prove that point, as ordinary law abiding citizens are only prevented to be able to defend themselves while criminals always have access to weapons. So gun control laws are flawed in principle and implementation.
On top of that, gun control laws is one of the primary tools for a oppressive state to control its citizens. No gun control laws simply means that the state & federal govt can not force their agenda on their people without having to contend with their firepower. Looking at known history of mankind, gun bans have always preceeded the purges and organized killings of citizens by their state.
Government can not grant you a thing, it can only take away from you what was yours to begin with. Gun control laws are perfect examples of that.
