We certainly cannot trust the federal nor state governments to protect us in any case of us not being armed. Hell, we all need to be armed with guns & lawyers, & then people might be more reluctant to get a gun & target mostly unarmed people if they are more liable to get shot for it, themselves.
Walking around without a gun or at least some weapon in this country should not be normal: it is not safe with most of us being unarmed except those who would commit violent crimes against us, including masses of corrupt government employees & public officials. We need inspectors general.
People obviously are not going to keep themselves honest in an unarmed population wherein courts routinely violate people's rights & lawyers don't even try to stop them, since we ultimately do not have real rights in this country but merely some have privileges as many have simply yet to discover...
