Sure, but I've probably locked it barely more than twice.
Likewise, but even if it's actually locked, no lock is impenetrable, and a closed garage provides a thief with the privacy to pick it at leisure or even break down the door. Burglary deterrence advice sometimes includes tips like adjusting your landscaping so your front door is visible from the street and locking gates to your back yard. Letting the thief into your garage thoroughly defeats the point of that...
Also, I keep stuff (bikes) in the garage that I don't want stolen.
Most people keep cars in their garage. Which last I checked were usually more expensive than bikes.
Joke aside, people keep a lot of valuable stuff in garages. Hell, tool chests can easily be worth thousands of dollars and are easy to pawn.
I've been thinking lately about how quickly the world has changed and I think it's a bit underappreciated. I mean cellphones only became a household item 20 years ago, smart phones about 15. Or closer to home, at least for me, generative models went from barely making small black and white human faces (Goodfellow invented GANs mid 2014) to being able to create some fucking good quality images on consumer hardware in a few minutes (not counting all the prompt engineering required. But unconditional is still pretty good). Not to mention that access to these things isn't homogeneously distributed and so rural and poorer regions tend to get thrown into the deep end rather than wade their way in. I think from that perspective a lot of drama makes sense. Especially when we're talking about how people are not very tech literate. Hell, I have a hard time convincing people in my CS PhD department that hate Facebook's spying to switch to Signal or even switch to FF (we see the same stuff here on HN. More excuses than explanations). If the "friction" (even if 90+% mental) is high among tech experts idk how novices can handle all this. At least with my family they're more willing to believe Facebook's app uses an always listening microphone rather than believe me when I explain that they can figure out you're friends and interested in gardening if you just stand next to someone or walk around with them for 30 minutes in the gardening section of Home Depot ¯\_(ツ)_/¯ (sorry, this took a tangent, but I know you think about some of these things too)
I don't know if that would do much.
It's one thing to be sawing up a front door that is in plain sight of the street -- passer-bys might call the cops if they saw that.
But if you're doing it from inside a garage? You could shut the garage door and saw away. Nobody would report saw noises coming from a garage because that's super normal.
1. I know it's a broad generalization, also location-dependant
Not sure where you live, but every house I've lived in (USA, a few different states) during my entire life has had an exterior-quality door with exterior-quality lock, including deadbolt, between the house and garage.
In the one house I lived in that had a security system, that garage-to-interior door was also wired into the system and arming it would treat it like an exterior door.
Having said that, I still wouldn't want random delivery people entering my garage without my knowledge.
