You should get them some full body Kevlar and chain mail as well. There are more shootings and stabbings than bicycle head injuries. Just to be safe.

Curious what sources you have.

Because several family members and I have experienced head injuries riding bicycles, none of us have been shot at or attacked with a knife. That said, I'm down for making all private gun possession illegal.

There's like 250,000 shootings and stabbings in the US per year estimated.

There's like 27000 bicycle head injuries in the US.

I'm surprised you haven't googled it.

Here's the head injury source. You can easily Google shooting and stabbings per year and add them together. https://www.nsc.org/safety-first-blog/bicycle-safety-statist...

Its pretty clear you should pick up some Kevlar and chain mail for your kids.

There may be some reporting issues with your data. For example how many helmets prevented would've-been-reported head injuries? How many injuries aren't reported? And how many hours on bicycle are there compared to constantly living around so many guns?

A natural experiment may require comparing similar communities with and with helmet laws.

Shootings and stabbings on the other had are difficult to not report. And can happen regardless of proximity to bicycles.

Ultimately let's do both: get helmets for kids and get rid of so many guns.
