From the details in the The Violence Project database. The following can be seen.
In six incidents, armed civilians were present at the location. (Armed
Police were present in 19 Incidents) out of 175 recorded incidents.
The average number of people who were killed and injured in these 175

Unfortunately, statistics based on actual events are not able to answer this question.
A working hypothesis is that a higher rate of gun ownership among targets will discourage potential shooters from trying. Similarly, easier access to guns will encourage potential shooters to try. The policy can clearly be counter-productive if only partially implemented, ...
There are several factors that make this a very difficult question to answer definitively.
What exactly is a "mass shooting"?
What exactly does it mean to stop a mass shooting?
How to account for mass shootings that are prevented by armed citizens, or even by the possibility that armed citizens will be present?

A 1967 law that prohibits members of the public from carrying guns on Capitol grounds was signed by President Lyndon Johnson. Regulations created by the police board days later exempted members of Congress from the law but still prohibited them from carrying firearms in either legislative chamber.
I don't think you have to worry about a political cost to yourself. The amount of money is trivial on the international scale, and the place to use and show an airgun is away from the public.
At least some European countries have strict safety and testing requirements for airguns which approach the limits of the weapons laws. Having an non-certified weapon ...
What political measures have proven effective around the world at reducing incidents of gun violence?
Infringing on the "rights" of normal people to carry firearms whose primary function is to kill other people seems to work quite well for the rest of the world (sample: UK, Australia). Yes, single-shot hunting rifles can kill people, but they can ...
There are two major problems with attempting to answer this question:
the absence of a uniform consensus of what constitutes a mass shooting
the lack of a consistent primary source of data spanning all incidents – attempted or otherwise partially / fully committed
That is to say, databases that track mass shootings record and publish data in uniquified ...
