How did the no gun policy at the Milwaukee Mall protect shoppers?

If “no gun” policies don’t work, why aren’t visitors to the Capitol and the White House allowed to carry guns. In fact why not allow guns on planes too?

Isn't there supposed to be a TRUMP SUPPORT rally near that mall on Saturday.

That wasn't a "mass shooter" situation. It started as a fight between 2 guys with concealed weapons. Putting MORE guns on the streets is not the answer to stop such violence. Reality check-- This isn't the Old West and you ain't Wyatt Earp.

When the first shots were fired, the "trained, armed citizens"  would have responded, then, while they were firing , other trained armed citizens would have seen them, and thought they were the original shooter and fired at them. Then, more armed citizens would enter the battle, thinking they could take down some of the terrorists that had entered the mall. By the end of the day, hundreds would have been shot, and the original shooter would have dropped his gun and ran away through a fire exit.

It is rare that some small penised individual who has to carry a gun everywhere to feel tough is actually going to do anything if someone starts shooting. They are more likely to panic, shoot themselves or some random person. 

The gunman probably didn't see the sign that said 'no guns allowed'. Honest mistake. They just need more signs
