As of last week, only 700 weapons have been turned over to New Zealand's government under new gun control laws written in haste in the wake of a mass shooting at Christchurch mosques. There are an estimated 1.5 million guns—with an unknown number subject to the new prohibition on semiautomatic firearms—in the country overall.
SHTFPlan mentioned the fact that Kiwis were disobeying the law, and things have still now changed. Gun owners in New Zealand have all but officially nullified the law by ignoring it.
And once again, it bears pointing out that responding to a horrendous crime by inflicting knee-jerk, authoritarian restrictions on innocent people proves to be an ineffective means of convincing people to obey the state.
