Well this is Joe Biden, the same man where many years ago he once told the general public to buy a double-barreled shotgun and shoot some rounds in the air to scare away any intruders for home defense.
This is terrible advice because any actual gun owner that knows what they're doing will tell you why this is stupid because a double-barreled shotgun can only fire two rounds which you have to reload afterwards and in a critical home defense situation you need to be fast if the intruders are armed and this is also dangerous because firing indiscriminately could also lead to a really bad accident because the projectiles will have to land somewhere and also this advice that Joe Biden gives is illegal because this is considered to be a reckless/negligent/unlawful discharge of a firearm in the U.S. as well.
And Joe Biden has also claimed that firearms such as an AR-15 are "harder to aim" and "harder to use" even though the recoil on those things is pretty much almost nonexistent in which makes them ideal for home defense while a shotgun (especially if it's a 12 gauge) will do a number on your own arms and hands because they do give a good kick when fired.
So why should anyone take any advice on firearms from Joe Biden anyway?
