If you are going to talk about the constitution and the second amendment, research it.
It was drawn up in 1791 and was about defending your land. A US High Court stated it did not give you the right to have any sort of gun anywhere.
.
I think you do not understand the bill of rights. The bill of rights does NOT grant ANY right. It assumes we were BORN with certain rights. The bill of rights prevents the government from taking those rights away. The second says NOTHING about hunting. Its about protecting one's life and liberty.
Your also wrong about the high court.
District of Columbia v. Heller, 554 U.S. 570 (2008), was a landmark case in which the Supreme Court of the United States held that the Second Amendment to the United States Constitution protects an individual's right to possess a firearm for traditionally lawful purposes, such as self-defense within the home and within federal enclaves.
The 7th U.S. Circuit Court of Appeals ordered the state in December to enact a law allowing concealed weapons, ruling that the ban in Illinois — the last state in the nation without such a law — was violating residents' constitutional right to keep and bear arms.
McDonald v. Chicago, 561 U.S. 3025 (2010), is a landmark[1] decision of the Supreme Court of the United States that determined whether the Second Amendment applies to the individual states. The Court held that the right of an individual to "keep and bear arms" protected by the Second Amendment is incorporated by the Due Process Clause of the Fourteenth Amendment and applies to the states. The decision cleared up the uncertainty left in the wake of District of Columbia v. Heller as to the scope of gun rights in regard to the states.
There are more people shot and killed EVERY WEEKEND in Chicago then in most of the mass shooting. Shootings in Chicago total more then all the mass shooting combined for the last 50 years. Chicago Is the last place in the US that a law abiding person CAN NOT carry a firearm, and one of the fee places in the country that you can't buy a firearm from a dealer.
About 20 years ago we had an "assault weapon" ban. It had a end date that was never renewed. The anti gun groups warned crime involving guns would sore. The opposite happend. The crime rate has declined year after year ever since, while the gun owners have increased. You might also note that Mass shooting occur in "NO GUN" zones. The theater shooting you mentioned- that nut job when 20 miles out of his way to go to a theater that had a "no guns" policy. Had he gone to one nearer his home, he made have been shot by someone with a concealed carry permit. And you don't mention the theater shooting in Texas. I guess because the not job there "only" shot two people before a woman with a canceled carry permit shot him.
Also I asume you have not seen all the studies that show an AR style weapon is one of the very best home defense weapons. Its much easier for people under great stress to hit targets with, the .223 round is less likely to over penetrate and go thru a wall to kill someone outside, and the recoil is much easier to handle- even for women and children.
All that said, I DO NOT own an AR. I chose to rely on the old 1911 pistol. And if I move closer to the city, I will get a short barrel pump shot gun. I don't want to shoot anyone, and there is no bad guy that doesn't recognize the sound of a pump being racked.
Finally, do you realize that you are 5X more likly to be a victim of home invasion then I am? Look up the stats- it true. Bad guys don't have to worry about being shot if they break into your house
