And, in England where there are strict gun laws, they have psychopathic migrants(forced upon them by the EU...to bring this thread back on topic), riding nuts-to-butts on scooters, and slashing and splashing the natives, and raping women in their own doorways, which could be discouraged by arming the natives...not by simply deputizing more RESPONDERS, who do nothing but accuse the natives of "racism," for daring to complain.
If you arm a population to deal with those migrants you create a whole set of other problems.
It is not a sustainable solution.
A more sustainable solution is stop bringing in low end migrants or as being done below;
In some Asian countries, for centuries there's always many movement of migrants, mostly the lowest of the low but they have in place draconian measures that quietly surpresses them into hiding a quite life - no schooling, constant deportation, constant visits by the police (who enjoys getting bribes), etc, you name it - it's done just to surpress em all.
But at the same time there's also a way out, if their local employer level up those migrants, meaning not only provide them with work permits but also educate them with recognised qualifications, this ensures those hard-working, clean, with roughly good virtues can attain permanent residency and even citizenship in their host country.
While the rest who can't cut it will be continously surpressed, too afraid to even cause much of a problem.
Meanwhile the citizens live a relatively safe environment without needing guns.
