The difference between being owning and being owned.

This short video loop is all you need to know about why people need to own guns.  In it, a small group of thieves took what was likely a stolen car and smashed in the iron security doors of a small clothing retail business.  The owner happened to be there at the time and he happened to have a loaded AR 15 under the counter.  Just as he struggles to get the gun out and ready to shoot, the thugs attempt to come racing in the recently busted in door.  They thought they were going to have a field day in there but instead the owner fired several shots in their direction and it sent the criminals scrambling like cockroaches under a lamp.

If it were up to the government, the store owner would be dialing 911 just about the time that one of those punks had made it to the front counter looking for the cash register, etc.  It's no stretch to believe that the criminals were probably armed and so the owner's life and property would be left to the mercy of the police response time.  This is just how the cops want it.  You are defenseless, they take their sweet ass time or don't even show up at all if getting paid by the gang doing the crime.

Cops are useless.  I which that were the worst of it.  They are actually dangerous and corrupt.
911 is thus useless.
Get a gun, learn how to use it and stay proficient.  Either that or you will eventually become a victim.
