This is a strawman. No one blamed cameras here, the cause for alarm is that facial recognition technology enables oppression at scale.
It should be still common sense to limit access to guns, so that people who are likely to harm themselves or others can't just go and buy one easily. Works very well in most of Europe.
If we're talking about fatalities then stats for gun deaths don't reinforce the argument that they are an unalloyed good, or that reducing their prevalence is impossible.
You seem to be arguing a point that was made by no one present in the conversation.
That aside, if you want to talk statistics, your biggest threat comes from the guns in the hands of your own country's police or military authorities. Sort of like the cameras under discussion.
I'm arguing against apathetic statements like restricting gun access is a "fatal distraction"
