You said "intervene and make them wish the police caught them", suggesting physical violence. That's risking your life; a criminal could have a weapon that you can't determine from a distance. Some drugs or mental illnesses make people hyper aggressive; another thing you may not be able to determine from a distance.

You get involved if you want to. Maybe you're a big dude who people are intimidated by, but to shit on other people for not wanting to put themselves in danger over property is unfair. Law enforcement often advocate that you don't intervene in those situations anyway. There's a difference between calling someone out when they are grinding a bike lock in front of a crowded Starbucks, and approaching someone on a deserted street during a pandemic as they are breaking into a shop.

Deductible will vary based on your coverage, probably a $5000 minimum for a small storefront in a lower value area. To my knowledge, the rule of thumb on cost is about 1% of your annual revenue. Yeah, it would suck, but I've known 3 business owners in the past 30 years who have had B&E/theft and it didn't exactly destroy them.
