Why do you doubt that?

As a counter data point, the police chief of Detroit recently advised the city's residents to carry guns for their protection. The reaction on right-wing blogs which covered this was applause.

Why you doubt it? In fact, that is exactly what is done when one wants to make absolutely sure nothing bad happens - a lot of people with guns come and saturate the area. Look what was done in New York on New Year's even or what happens when the President or other VIP like that visits some place. Lots of people with guns are always around. So apparently if you look at evens through the lens of "how many guns are around", "more guns" is the common standard solution for "more security".

I am.
