Some people do carry knives for self defense. IDK if they want to "throw them", that would be their problem.
Blow guns are innefective "stopping power" wise unless you poison the darts and even in self defense, using poison is a premeditation that you really don't want being brought up in court.
Since most violent criminals are carrying firearms, countering them with at least equal force is the most popular choice when available.
How about people who aren't as healthy or handy with their fists as we? You really expect an octagnerian woman in a wheel chair to knife fight with a mugger?
Disparate physical ability and standoff range is what firearms are made for. Plain and simple. They put a single weakling on even footing with a carfull of armed thugs. Pocket knives do not do that.
Anyways, that reason is exactly why I don't want to see legislation that is designed to make currently law abiding innocent citizens into fellons under threat of arms overnight. (An actual goal of the Brady Bunch.)
Our government is technically "of the people, for the people and by the people". That means that the laws which apply to us should in theory apply to them equally.
This has been co-opted by corrupt lawmakers themselves, but that is no reason to simply let the noble principles of equality and self determination slide down the drain.
The whole "RTKBA" things is intended to empower us should we have to assert our rights via force of arms. The second amendment is the teeth behind amendments three through nine.
BTW, the most devastating weapons of the era were owned by private citizens in the Revolutionary war and the war of 1812 (British invasion). Lafitte owned a damn navy! So don't try to tell me the founding fathers didn't intend for us to be armed with the state of the art when some of our greatest assest against the Empire were heavily armed private citizens.
However, Lafitte had a place to use his Navy and reason to use it. Which brings us to this;
Personally, I support "responsible gun ownership". I know that I have no responsible way to store or opperate a TOW missile. (**** son, just finding a rifle range long enough to stretch the legs of a decent bolt action is a challenge. Where are you going to paractice with your TOW missile?) I personally don't have a use for one and wouldn't spend the money even if one was available.
If the situation arises there will probably be a TOW or two in theater for the occasion. Anti tank weapons seem to follow tank battles around. I dunno. You tell me...
However, 30 round magazines can be and are owned responsibly by the common people. So are semi autos of all types. In a riot situation (see Katrina) I would not want to be armed with less.
How's that for brains?
As for teeth? Mine are sharp as a sharks. Just ask the last stupid **** that tried to rob me.
