How can we send a reward/present to Charles Russell, the Instacart shopper who protentially stopped a mass shooting in Atlanta recently?

Here is a news video of the incident. Instacart shopper
His quick thinking saved who know how many lives and millions of dollars.
I want to send him something for stepping up to the plate and doing the right thing.
PM me if you can find contact info.

Bonus points: what laws would have reduced the chances of this happening.
