Does reading a lot of Wikipedia give people a wrong idea how science works?

[Jackalope]

I wonder, how many would constitute a problem that we should, you know, do something about?

That is like asking how high somebody's body temperature has to be before you try bloodletting. You should not try bloodletting until you have solid mechanistic evidence that it works. Similarly, you should not try banning high-tech weapons and preventing mentally ill people from owning a firearm (which is what "gun control" essentially means) before you have solid mechanistic evidence that it would do anything to decrease mass shootings.

Congratulations, you've deflected on the question just like every other delusional gun nut before you, as expected.

We do have such evidence. I suggest you spend more time looking at the issue objectively and less time thinking up absurd analogies and fellating Kleck.

(Before you ask, no, I am not here to do work for you.)

ETA: I also note that you immediately jumped to the conclusion that "doing something about it" == "gun control". I suggested no such thing. The question was crystal clear as asked as was your deflection.
