It made me so mad when I heard about that ‘lady’ (I could think of a lot more insulting and crude terms she deserves to be called).The Swiss Guard should have dragged her outside and beaten her to within an inch of her life and then drag her bloody, bruised and beaten down body in front of the cameras to show others that you don’t mess with the Pope.
In fairness to the Swiss Guard and whoever else was handling security (i.e. Italian police or something), it is virtually impossible to defend against the lone unarmed attacker. Obviously, metal detectors, x-rays, dogs, etc. can detect most weapons if employed properly. Also, a good Intelligence section can help try to unravel any potential conspiracies, but the lone whackjob is very difficult to defend against if they unarmed since there is no red flags that might pop up.
Unless you are going to have His Holiness covered with more linebackers than a quarterback at the Super Bowl or going to keep him in an underground bunker all day, the best way to minimize this sort of stuff is to make a strong object lesson of anyone who dares try to assault the Pope. The next time we see this woman, she should look like she went several rounds with a grizzly bear. Even deranged individuals will recognize that old saying: pain hurts a lot.
Again, I hope the Pope and the Cardinal are both okay.
