The answer is because they know Americans are ARMED to the teeth.

Don't put to much stock in that preventing something like this in the USA.

Lets say on an average day at the average mall there are 2000 people at the mall. Of those 2% have CCWs because they ignore the gun-free zone signs.

I am sure they could have some positive effect perhaps even taking out a few of the scumbags, but in the end the death toll would still be very high.

The scumbags want to die, they have no fear of death.

The only way to prevent this happening here is to ensure that they never, never enter the US in the first place. But thanks to our wonderful congress writing insane immigration policy the gates are wide open and its only a matter of time.

The only other way to prevent such carnage, other than for the fact that Americans ARE ARMED to the teeth, is to do what Israel has done, BUILD a massive wall on both borders. But I am not holding my breath on that

The only way to prevent this happening here is to ensure that they never, never enter the US in the first place.

Two Points:

1) 5 of those scumbags friggin' CAME FROM THE USA!

2) Take care about potential solutions...

It's the TSA's wet dream to have checkpoints EVERYWHERE!
